Question

A physics student on Planet Exidor throws a ball, and it follows the parabolic trajectory shown in Figure 63. 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 v_x = 2.0 m/s, v_y = 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?
