A physics student on Planet Exidor throws a ball, and it follows the parabolic trajectory shown in Figure EX 4.11. The ball’s position is shown at 1s intervals until t = 3 s. At t = 1 s, the ball’s velocity is v(vector) = (2.0î + 2.0ĵ) m/s.

a. Determine the ball’s velocity at t = 0 s, 2 s, and 3 s.

b. What is the value of g on Planet Exidor?

c. What was the ball’s launch angle?
