###### Problem Details

A physics student on Planet Exidor throws a ball, and it follows the parabolic trajectory shown in the figure . 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.
