A stone is thrown horizontal with a velocity of 40.0 m/s from a top of a building find its velocity and displacement after 3.00 seconds

Question

Guys need your help

Answer 1

the horizontal speed is constant at 40 m/s, so the x di
The vertical position at time t is h - 4.9t^2, where h is the height of the building.
The vertical velocity is of course, -9.8t
So plug in t=3 and crank it out.
