A ball of mass .0750kg is traveling horizontally with a speed of2.20 m/s. It strikes a vertical wall and rebounds horizontally. Dueto the collision with the wall, 20% of the ball's initial keneticenergy is dissipated.

A:Show that the ball rebounds from the wall with a speed of 1.97m/s^-2

For this part i assumed that the ^-2 was a typo and was meant tojust be ^2.
However, my work is wrong and my teacher never taught us thisinformation. What i did was divided the initial speed of 2.20M/s by.8 since it losses 20% of its energy when it hits the wall,however, this give you an answer of 1.76 m/s. can someone show mehow to do this correctly or show me where i went wrong?

First question: A handball of mass .10 kg, travels horizontally at25.0 m/s, strikes a wall and rebounds at 19.0 m/s. What is thechange in the momentum of the ball?
Answer is: 4.4 N (s)

Second questions: A bullet of mass 20 g, traveling at 350 m/s,strikes a steel plate at an angle of 30 degrees with the plane ofthe plate. It ricochets off at the same angle, at a speed of 320m/s. What is the magnitude of the impulse that the wall gives tothe bullet?
Answer: 6.7 N(s)

Third question:
