A ball falls from 0.45m in the air and hits the ground, calculate the impact velocity, second assume a 35% loss of energy on impact, what height does it return to?
I need this urgently please if anyone can answer​

If the ball didnt lose energy, it would return to the original height, but because it lost 35% of it energy, it would return to this height:

0.45 - (0.45 x 35%
