A stone is thrown vertically up from the top of a tower with a certain initial velocity. It reaches ground in t seconds .(7.65). A second stone, thrown down from the same tower with the same initial velocity reaches ground in 3.6 seconds. Determine (i) the height of the tower, and (ii) the initial velocity of the stones.

A stone is thrown vertically upward with an initial velocity of 20 m/s. Air resistance is considered negligible. (1) At what time does it reach the peak? (2) What is the maximum height it reaches? (3) What is speed of the stone just before it hits the ground? The velocity of a 1-kg particle moving along the x axis changes from vi = -2m/s to vf = -5m/s in 3s. (1) What are the change in momentum and impulse for...
