A sports car accelerates at a constant rate from rest to a speed of 27. 8 m/s in 8. 00 s. What is the displacement of the sports car in this time interval?.

Answers

Answer 1

The displacement of the sports car is approximately 222.4 m. This is the distance traveled by the car in the 8.00 s time interval, assuming that it accelerates at a constant rate.

To calculate the displacement of the sports car, you will need to know its acceleration as well as its initial and final velocities. Displacement is defined as the change in position of an object, and it can be calculated using the equation:

Displacement = (Final Velocity + Initial Velocity) / 2 * Time

In this case, the initial velocity of the sports car is 0 m/s (since it is starting from rest) and the final velocity is 27.8 m/s. The time interval is 8.00 s. Plugging these values into the equation above, we get:

Displacement = (27.8 m/s + 0 m/s) / 2 * 8.00 s

This simplifies to:

Displacement = 27.8 m/s / 2 * 8.00 s

This further simplifies to:

Displacement = 27.8 m/s * 8.00 s / 2

This simplifies to:

Displacement = 222.4 m

So the displacement of the sports car is approximately 222.4 m. This is the distance traveled by the car in the 8.00 s time interval, assuming that it accelerates at a constant rate.

If you had pulled the box with 300W of power, and did 900J of work, how long did it take to pull the box?

Answers

Answer: 3 seconds

Explanation:

The equation for Power is  P=W/tΔ

P= Power(W)

W= Work(J)

t= change in time

So for this equation we have 300=900/t where we need to solve for t which we can do by using algebra

300=900/t

t=900/300

t=3

so t= 3 seconds (s)

You observed the wheels of a car as it moves past you from right to left. Do the wheels have a positive or negative angular velocity?

Answers

Answer:

Negative angular velocity

Explanation:

The movement/rotation  of An object in a clockwise direction ( right to left direction)  corresponds to a Negative angular velocity . while the rotation of an object in an anti-clockwise direction ( left to right direction ) possess  a positive angular velocity.

Hence the movement of the wheels of the car past you from right to left will possess a Negative angular velocity

A toy gun uses a spring to shoot plastic balls (m = 50 g). The spring is compressed by 3.0 cm. Let k=2.22 × 105 N/m. (a) Of course, you have to do some work on the gun to arm it. How much work do you have to do? (b) Suppose you fire the gun horizontally. How fast does the ball leave the gun? (c) Now suppose you fire the gun straight upwards. How high does the ball go?

Answers

Answer:

Explanation:

Given that:

mass of the plastic ball = 50 g = 50 × 10⁻³ kg

spring constant (k) = 2.22 × 10⁵ N/m

compression of spring (x) = 3.0 cm = 3 × 10⁻² m

a) Work done:

[tex]= \dfrac{1}{2}kx^2 \\ \\ = \dfrac{1}{2}\times 2.22 \times 10^{5}\times (3 \times 10^{-2})^2 \\ \\ = 99.9 \ J[/tex]

b) When the gun is fired horizontally;

In the spring, the potential energy is changed to kinetic energy.

i.e.

[tex]\implies \dfrac{1}{2}kx^2 = \dfrac{1}{2}mv^2 \\ \\ 2.22 \times 10^5 \times (3\times 10^{-2}) ^2 =50 \times 10^{-3} \times v^2\\ \\ \mathbf{v= 63.2 m/s}[/tex]

c) The max height the bullet will reach if the gun is being shot upward is:

[tex]H_{max}= \dfrac{v^2}{2g} \\ \\ H_{max}= \dfrac{63.2^2}{2\times 9.8}[/tex]

[tex]\mathbf{H_{max}= 203.9 \ m}[/tex]

• Select Rulers to measure the amplitude of the waves.
For each measurement described below, pause the wave when the oscillator arm is at or just past its maximum

You can see that each wave has a crest and a trough. Measure the amplitude at the first crest to the center of the ball and record your reading in
the table below. Record amplitude measurements for every subsequent trough and crest, as identified in the table.
Finally, vary the Damping as indicated in the table and record your amplitude readings again for each different damping value to complete the

Thomas helps his older brothers, who own a junk yard, on the weekends to earn extra money. He likes to help them push broken-down cars to the back of the junk yard because it makes him feel strong. Last Saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. The cars were the following weights:white car: 2,700 poundsred car: 1,500 poundsblue car: 2,100 poundsThink about how much force is needed to move each car. Which correctly organizes the cars in order from the most to least amount of force needed to move them

Answers

Answer:

white, blue and red

Explanation:

Force is given by

[tex]F=ma[/tex]

where

m = Mass of object

a = Acceleration of the object

If the acceleration is same for all the cars the force needed to be applied will depend on the mass of the car. The heaviest car requiring the most force and the lightest car requiring the least amount of force.

Here, the weight of the cars in descending order is white, blue and red.

So, the cars in order from the most to least amount of force needed to move them is white, blue and red.
