a piano of mass 852 kg is lifted to height of 3.5m how much gravitational potential energy is added to the piano acceleration du
e to the gravity is g=9.8 m/s2
1 answer:
Gravitational potential energy added =
(mass) x (gravity) x (distance lifted)
= (852 kg) x (9.8 m/s²) x (3.5 m)
= (852 x 9.8 x 3.5) kg-m²/s²
= 29,223.6 joules
