A ball is thrown vertically upward with an initial speed of 15 m/s from 80 m above the ground. Assume free fall conditions. (a) What is the max height? (b) Determine the magnitude of the velocity at 40 m above ground. (c) At what speed does the ball strike the ground?
Two canons are fired at the same time from the origin. The two canons are fired at time t=0, with two initial speed V initial 1=20 m/s and v initial 2=40 m/s the initial velocity of the first bullet makes an angle=45 degrees while the other one makes an angle=40. Will the two bullets meet?
