The height above the ground (in feet) of a stone t sec after it is dropped from a bridge 752 ft above ground is given by the polynomial 752 - 1612 a. Factor the polynomial. b. Use the factored form in part (a) to find the height of the stone 6 sec after it is dropped. a. 752 - 1612-0 b. The stone is ft above the ground 6 sec after it is dropped. Enter your answer in each of...
An object of mass m is dropped from height h above a planet of mass M and radius R. Find an expression for the object's speed as it hits the ground. Express your answer in terms of the variables m, M, h, R and appropriate constants.

A ball is dropped from a height 24 m above the ground at t=0.0. Each time it bounces from the ground, its rebound speed is 60% of its impact speed. At the instant the first ball hits the ground, a second ball is released from the same place. Take g = 9.8 m/s2. At what height above the ground will they collide? (Take the ground as y=0.0 m)

At t = 0, a stone is dropped from a cliff above a lake; 2.4 seconds later another stone is thrown downward from the same point with an initial speed of 47 m/s. Both stones hit the water at the same instant. Find the height of the cliff.
At t = 0, a stone is dropped from a cliff above a lake; 2.4 seconds later another stone is thrown downward from the same point with an initial speed of 35 m/s. Both stones hit the water at the same instant. Find the height of the cliff in meters.
part 1 of 3A tennis ball is dropped from 1.79 m above the ground. It rebounds to a height of 1.01 m. With what velocity does it hit the ground? The acceleration of gravity is 9.8 m/s2. (Let down be negative.) Answer in units of m/s. part 2 of 3 With what velocity does it leave the ground? Answer in units of m/s. part 3 of 3 If the tennis ball were in contact with the ground for 0.0126 s. find the acceleration given to the...
