Physics

A rock is thrown off a cliff with a vertical speed of 53 m/s upward and a horizontal speed of 30 m/s.

A) what will these speeds Vx and Vy, be 4 seconds later?
B) what will be the x and y displacements of the rock be 4 seconds later?

  1. Vx is constant at 30
    Vy = 53-9.8t

    x(t) = 30*t
    y(t) = 53t - 4.9t^2
