Problem 13CQ

Answer the following questions for projectile motion on level ground assuming negligible air resistance (the initial angle being neither 0º nor 90º): (a) Is the velocity ever zero? (b) When is the velocity a minimum? A maximum? (c) Can the velocity ever be the same as the initial velocity at a time other than at t = 0 ? (d) Can the speed ever be the same as the initial speed at a time other than at t = 0 ?

Solution

Step 1 of Step 5

To this problem we will assume projectile motion equation and a small figure how it works. The figure is given below, A player heating a football in the air from the ground.
