_____________________
Total energy of the ball = potential energy + kinetic energy
potential energy = mgh
= (50/1000) kg × 9.8 m/ s² × 5.5 m
= 2.695 joules
Kinetic energy = (1/2)×m×v²
= (1/2) × (50/1000) kg × (10m/s)²
= 2.5 joules
Total energy of the ball the moment it throws the window = ( 2.695 + 2.5 ) = 5.195 joules.
