If the same ball is dropped from 10 feet and is caught exactly at the highest point after the 25th bounce,what is the total distance traveled by the ball?

If you were to drop a large log over the edge of the Grand Canyon and it took 3.21 seconds to hit the ground, calculate the velocity of the log at impact in m/s.

(a) How long would it take an object to fall 100m on the moon (g = 1.6m/s/s) if dropped from rest?  (b) How fast would it be going after 100m?

6) The cannon on a battleship can fire a shell a maximum distance of 21.6 km.   (a) Calculate the initial velocity of the shell in meters per second. (Enter the magnitude.) _____ m/s   (b) What maximum height in meters does it reach? (At its highest, the shell is above a substantial part of the atmosphere—but air resistance is not really negligible as assumed to make this problem easier. Assume the shell has been fired so as to maximize horizontal distance.)  _____m   (c) The ocean is not flat, because the earth is curved. Assume that the radius of the Earth is 6.37 ✕ 103 km. How many meters lower will its surface be 21.6 km from the ship along a horizontal line parallel to the surface at the ship? _____ m   Does your answer imply that error introduced by the assumption of a flat Earth in projectile motion is significant here? (Select all that apply.) _The error is insignificant compared to the size of a target. _The error could be significant compared to the size of a…
