Answer: PE = 800j, KE = 800J
Explanation:
To calculate the potential energy, we use the formula
Potential Energy = Mgh
M = 20kg, g = 10m/sˆ2 , h = 4m
=20 × 10 × 4
=800J
At the maximum height S = 4 and the initial velocity u = 0 The acceleration g = 10m/sˆ2
Using the third equation of motion
vˆ2 = uˆ2 + 2as
= 0ˆ2 + 2 × 10 × 4
vˆ2 = 80
Kinetic Energy (KE) is given by
KE = ½ mvˆ2
= ½ × 20 × 80
=800J
