Question

A particle travels between two parallel ver-
tical walls separated by 39 m. It moves to-
ward the opposing wall at a constant rate of
8.8 m/s. It hits the opposite wall at the same
height.
The acceleration of gravity is 9.8 m/s2 .
39 m
9.8 m/s2
8.8 m/s
a) What will be its speed when it hits the
opposing wall?
Answer in units of m/s
