Answer:
20m/s final velocity, 60meters is the distance
Explanation:
since it accelerates 4m/s we can assume every second it goes up by 4 so we do 5×4=20...
while for the distance we have to think about the fact that every second the speed changes (precisely every second adding 4m/s) so in the first second its going to travel 4 meters in the second 8m in the third 12m in the fourth 16m and in the fifth 20m... so we just calculate them for addition and get 60 meters

how long does it take the star and planet to complete one orbit around their center of mass?
Answer:
i think about 225-250 million years
Explanation:
Bottom line: The planets in our solar system orbit (revolve) around the sun, and the sun orbits (revolves) around the center of the Milky Way galaxy. We take about 225-250 million years to revolve once around the galaxy's center. This length of time is called a cosmic year.

If a male runner in the fourth starting position ran the 400 m race in 44.40 s, how would you
calculate his average speed?
If a male runner in the fourth starting position ran the 400 m race in 44.40 s, then for calculating his average speed we have to divide the total distance covered by the time taken by him to cover the distance.
His average speed would be 9.0 meters/second.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second. The generally considered unit for speed is a meter per second.
The mathematical expression for speed is given by
speed = total distance /Total time
If a male runner in the fourth starting position completed the 400 m race in 44.40 s, we must divide the total distance traveled by the amount of time it took him to complete the course to get his average pace.
the average speed of the runner = 400 meters/44.40 seconds
= 9.0 meters/second
Thus, his average speed.be his average speed would be 9.0 meters per second

How far has a ball traveled after 3.6 seconds when thrown downward at a
velocity 3.75 m/s?
ball traveled 13.5 m/s after 3.6 seconds
Explanation:
u=3.75m/s, t=3.6s, g=9.8m/s².
Therefore, according to the formula,
S=ut+½gt².
S=(3.75×3.6)+½×9.8×(3.6)²
S= 13.5+63.504
S= 77.004m (approximately 77 m)
therefore the distance traveled by the ball is 77m.

Three astronauts guide a 100 kg asteroid safely away from their space capsule. The first astronaut pushes with a 35 N force directed 45 degrees below the x-axis. The second astronaut pushes with a 35 N force directed 45 degrees above the -axis. The third astronaut pushes with a 35 N force along the x-axis. Calculate the magnitude of the net force exerted by the three astronauts. Calculate the rate (magnitude only) at which the asteroid's velocity changes.
The magnitude of the net force exerted by the three astronauts is 84.5 N and the rate at which the asteroid's velocity changes is 0.845 m/s².
The given parameters;
mass of the asteroid = 100 kgforce by first astronaut = 35 N, at 45 degrees below x -axisforce by second astronaut = 35 N, at 45 degrees above x-axisforce by third astronaut = 35 N, at 0 degrees on x-axisThe resultant horizontal force applied by the three astronauts on the asteroid is calculated as;
Fₓ = 35cos(45) + 35cos(45) + 35cos(0)
Fₓ = 84.5 N
The rate at which the asteroid's velocity changes is calculated as;
[tex]F = ma = m\frac{\Delta v}{\Delta t} \\\\\frac{\Delta v}{\Delta t} = \frac{F}{m} \\\\\frac{\Delta v}{\Delta t} = \frac{84.5}{100} \\\\\frac{\Delta v}{\Delta t} = 0.845 \ m/s^2[/tex]
Thus, the magnitude of the net force exerted by the three astronauts is 84.5 N and the rate at which the asteroid's velocity changes is 0.845 m/s².

A 700 g block is released from rest at height h0 above a vertical spring with spring constant k ! 400 N/m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 19.0 cm. How much work is done (a) by the block on the spring and (b) by the spring on the block
The work done by the block on the spring and by the spring on the block is 7.22 J.
The given parameters;
mass of the block, m = 0.7 kgspring constant, k = 400 N/mextension of the spring, x = 19 cm = 0.19 mBased on law of conservation of energy, the potential energy of the block will be converted to elastic energy of the spring, producing the given extension.
The work done by the block on the spring will be equal to work done on the block by the spring.
[tex]W = \frac{1}{2} kx^2\\\\W = \frac{1}{2} \times 400 \times 0.19^2\\\\ W = 7.22 \ J[/tex]
Thus, the work done by the block on the spring and by the spring on the block is 7.22 J.

Describe what happens when there is Friction and you stop pushing on an object?
Are your answers to questions 1 and 2 the same? Why or why not? What causes that to be the same or different?
I give Brainliest!
Answer: see below
Explanation:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Friction opposes relative motion. In its absence, a moving object will not stop.
2) If you stop pushing, the force of kinetic friction will produce an acceleration in the opposite direction of the velocity, and the object will slow down and stop.
3) No they are not the same, as one has friction and the other has no friction.

What is speed?Speed is distance travelled by the object per unit time. Due to having no direction and only having magnitude, speed is a scalar quantity With SI unit meter/second.
Given parameters:
Mass of the ball: m = 0.50 kg.
Initial speed of the ball: v = 6.0 m/s.
A) its kinetic energy at initial = 1/2mv² = 1/2 × 0.50 × 6.0² Joule = 9.0 Joule.
B) As total energy is conserved., when the ball reaches its maximum height its initial kinetic energy fully transforms into potential energy. Its maximum gain of potential energy is its kinetic energy, that is, 9.0 Joule.
C) Its maximum gain in height be = √(v²/2g) = √(6.0²/2×9.8) m = 1.91 m.
