Answer:

Explanation:
Given that,
The masses of two objects, m₁ = m₂ = 1 kg
The distance between masses, d = 1 m
We need to find the gravitational force between two masses. The force is given by the relation as follows :

So, the force between two masses of 1 kg is
.
Answer: g = acceleration = A*w^2 = A*(2*pi*fb)^2.
Explanation:
The ball bounces when the acceleration of the ball exceeds that of gravity. If A and fb are measured at that point, g = acceleration = A*w^2 = A*(2*pi*fb)^2.
Answer:
the formula for calculating acceleration is ending speed minus starting speed divided by time.
