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
