We previously decided that if I were to shoot a 30 g bullet at 500 m/s with a shotgun, I would roll backwards at 0.214 m/s on my wheeled platform. If kinetic friction coefficient of my platform is 0.05, how far will I roll back before I stop in m

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
