Answer:
1600j
Explanation:
PE = mass * gravitational acceleration * hight
PE = 20 * 10 * 8
PE = 1600 joules
The answer is 350J
acceleration due to gravity(g) =10ms-2
now the formula of gravitational potential energy is
U=mgh
acceleration due to gravity(g) =10ms-2
now the formula of gravitational potential energy is
U=mgh
