A 0650 kg projectile is launched from the edge of acliff, Ask an Expert

Academics

A 0.650 kg projectile is launched from the edge of acliff with an initial kinetic energy of 1650 J and at itshighest point is 85.2 m above the launch point. What is thehorizontal component of its velocity?

What was the vertical component of its velocity just after launch?

At one instant during its flight the verticalcomponent of its velocity is 22.75 m/s. At that time, howfar is it above or below the launch point?
