A particle travels between two parallel vertical walls separated by 11 m. It moves toward the opposing wall at a constant rate of 5.2 m/s. It hits the opposite wall at the same height.

The acceleration of gravity is 9.8 m/s2.

a) What will be its speed when it hits the

opposing wall?

Answer in units of m/s

b)At what angle with the wall will the particle strike?
