A stone of mass 0.750 kg is launched vertically upward, from the
ground, with an initial velocity of 18.0 m/s.
(a) Determine the average power consumed by the gravitational force
during the time it moves from the ground to 12.0 m above the
ground?
(b) Determine the instantaneous power being consumed by gravity
when it first reaches 12.0 m above the ground?

A stone with mass m = 0.700 kg is thrown vertically upward into the air with an initial kinetic energy of 610 J. The drag force acting on the stone throughout its flight is constant, independent of the velocity of the stone, and has a magnitude of 0.600 N. What is the maximum height reached by the stone? What is the speed of the stone upon impact with the ground?
show work 4. Suppose a stone is launched vertically upward with initial velocity 32 ft/sec from a height of 48 ft above ground. After t seconds its height is given by s(t) = -16t2 + 32t + 48 At the time when the stone hits the ground it is moving with a speed of A. 32 ft/s B. 24 ft/s C. 64 ft/s D. 48 ft/s E. 96 ft/s
PLEASE ANSWER COMPLETELY A projectile of mass m launched vertically upward from the origin (0,0) with an initial velocity of vo explodes into three pieces when it reaches its maximum height of 490.0 m. Immediately after the explosion, one piece with mass m/4 is observed to have velocity v 3vot vo/2 y, and a second piece also of mass m/4 is observed to have velocity v Vox (a) What is the velocity v of the third piece immediately after the...
A stone thrown from the top of a building is given an initial velocity of 20.0 m/s straight upward. The stone is launched 50.0 m above the ground, and the stone just misses the edge of the roof on the way down. Determine a.) the time needed for the stone to reach the ground b.) the velocity of the stone at t = 5.00s, with the position being -27.5 m

You throw a stone vertically upward with an initial speed of 6.1 m/s from a third-story office window. 1)If the window is 13 m above the ground, find the time the stone is in flight. 2) Find the speed of the stone just before it hits the ground.
A stone thrown from the top of a building is given an initial velocity of 20.0 m/s straight upward. The stone is launched 50.0 m above the ground, and the stone just misses the edge of the roof on the way down. 1. Using t=0 s as the time the stone leaves the thrower's hand at position, determine the time at which the stone reaches its maximum height. 2. Find the maximum height of the stone 3. Determine the velocity...

The stone is launched 60.0 m above the ground, and the stone just misses the edge of the roof on its way down. a. Find the maximum height of the stone. b. Using t=0 as the time the stone leaves the thrower’s hand, determine the time at which the stone reaches its maximum height c. Find the velocity and position of...
A young girl threw a 1 Kg stone vertically upward into the air. Her hand moved through a distance of 0.5 m before the stone left her hand. If the stone reaches a maximum height of 20 m above her hand’s starting point, what force did she apply to the stone? Assume the force was constant and ignore air resistance.
Two stones are thrown vertically upward from the ground, one with three times the initial speed of the other. Assume free fall. If the faster stone takes 11.0 s to return to the ground, how long will it take the slower stone to return? If the slower stone reaches a maximum height of H, how high (in terms of H) will the faster stone go?
