For the first part of this question I got 12.12m/s

B. With the help of a friend the boy measures the height to which the ball returns and finds it to be 5.2 meters. How fast was the ball moving when it left the ground?

I wrote this down

mass of ball: 0.40kg

height if house: 7.5

gravity: 9.8m/s^2

v1: 12.12m/s

Help please
