A physics student on Planet Exidor throws a ball, and it follows the parabolic trajectory shown in the figure. The ball's position is shown at 1.0 s intervals until t = 3.0 s. At t = 1.0 s, the ball's velocity has components vx = 2.0 m/s, vy = 2.0 m/s.
a. Determine the x- and y- components of the ball's velocity at t = 0.0 s, 2.0 s, and 3.0 s.
b. What is the value of g on Planet Exidor?
c. What was the ball's launch angle?
