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= 1.5 m/s, Vy = 3.0 m/s.
1. Decide the x-and y-components of the ball's velocity at t = 0.0 s.
2. Decide the x-and y-components of the ball's velocity at t= 2.0 s.
3. What is the value of g on Planet Exidor?
4. What was the ball's launch angle?
