Question

A body is projected horizontally from the top of a tower with initial velocity 18 m/s. It hits the ground at angle 45°. What is the vertical component of velocity when it strikes the ground?

G1 Physics · Accepted Answer

The horizontal component remains 18 m/s. At impact the velocity makes 45° with the horizontal, so |vᵧ| = vₓ = 18 m/s.
