Problem Details

A physics student on Planet Exidor throws a ball, and it follows the parabolic trajectory shown in the figure A figure shows the parabolic trajectory of a ball on the xy-plane. No explicit coordinates or units are given. Four ball’s positions are depicted. At the time of 0 seconds, the ball is at the origin. At 1 second, the ball is on the uprising part of the parabola. A velocity vector for that moment is drawn. The two seconds mark is at the apex of the trajectory, and the three seconds mark is on the descending part of the parabola at the same height as the 1 second point.. The balls position is shown at 1s intervals until =3s. At =1s, the balls velocity is =( 2.0+ 2.0 )/s.

Determine the balls velocity at =0.

Determine the balls velocity at =2s.

Determine the balls velocity at =3s.

What is the value of on Planet Exidor?

What was the balls launch angle?
