What is the mathematical relationship between these three values? 0.78 seconds, -9.81 m/s^2, and -7.68 m/s. I need help with this, please.
The mathematical relationship between time, acceleration and velocity is given by: [tex]Acceleration = \frac{v\;-\;u}{t}[/tex]
In Physics, the acceleration of an object or body can be defined as the rate of change of velocity with respect to time.
Hence, acceleration is calculated by subtracting initial velocity from the final velocity and dividing by the time.
Mathematically, acceleration is given by the formula;
[tex]Acceleration = \frac{v\;-\;u}{t}[/tex]
Where:
v is the final velocity measured in meter per seconds (m/s).u is the initial velocity measured in meter per seconds (m/s).t is the time measured in seconds.Also, the acceleration of an object or body is measured in meter per seconds squared ([tex]m/s^2[/tex]).

What is the average velocity of a car that drives 50 meters to the left in 5 seconds?
Answer:
[tex]\boxed {\boxed {\sf 10 \ m/s \ left}}[/tex]
Explanation:
Velocity is the speed of something in a given direction. It is a vector quantity, so it has both magnitude and direction. Velocity is calculated by dividing the displacement by the time.
[tex]v= \frac{d}{t}[/tex]
The car drives 50 meters to the left in 5 seconds.
d= 50 m left t= 5 sSubstitute the values into the formula.
[tex]v= \frac{50 \ m \ left}{5 \ s}[/tex]
Divide.
[tex]v= 10 \ m/s \ left[/tex]
The average velocity of the car is 10 meters per second to the left.
A simple pendulum is made of a small blob of mass m=7.000 kg attached to the end of an inextensible wire. The angular amplitude of oscillation is θ=5.730°. Consider that the gravitational acceleration is g=9.807 m/[tex]s^{2}[/tex]. What is the magnitude of the tension in the wire when the blob is directly below its point of support?
Answer:
The tension must be equal to the weight of the bob plus the centripetal force that is provided at eth end of the motion.
h = L (1 - cos theta) where h is the height to which the bob is raised
cos 5.730 = .995
h = .005 L
Also 1/2 m v^2 = m g h speed of the bob at the bottom
v^2 = 2 g h = .01 g L where 2 h = .01 L
v^2 / L = .01 g
m v^2 / L = .010 g m = .07 g since m = 7
Total tension = m g (1 + .07) = 1.07 m g
T = 9.807 * 1.07 * 7 = 73.45 kg m / s^2

3. a) If the distance between two objects increases by a factor of 5 (5),
does the gravitational force between the objects increase or decrease?
By what factor does the gravitational force between the objects
change?
b) If the mass of one object decreases by a factor of 3 (*1/3), does the
gravitational force between them increase or decrease? By what factor
does the gravitational force between the objects change?
Answer:
Answer for A
Explanation:
F1=GmM/r1^2
If r2 becomes r2=5r
F2=GmM/(25r^2)
Multiply with 25 gives to maintain the same force
I.e.,25F2=F1
F2=G(25m)M/25r^2=F1
By the factor 25 would change to increase to same.

seconds at a rate of 1.20 m/s2. If
the final velocity is 30.0 m/s, what
was its starting velocity?
Answer:
Vi=15.6m/s
Explanation:
a=(Vf-Vi)/t
when we find Vi from the above formula
Vi = Vf - at
Vi=30m/s - 12sec×1.2m/s^2
Vi = 15.6m/s
