Given Information:
Mass of elephant = m = 750 kg
Height = h = 14.3 m
time = t = 30 seconds
Required Information:
Power needed to lift elephant = P = ?
Answer:
Power needed to lift elephant ≈ 3507 watts
Step-by-step explanation:
As we know power is given by
P = PE/t
Where PE is the potential energy and t is the time
Potential energy is given by
PE = mgh
Where m is the mass of elephant, g is the gravitational acceleration and h is the height to lift the elephant.
PE = 750*9.81*14.3
PE = 105212.25 Joules
Therefore, the required power to lift the elephant is
P = PE/t
P = 105212.25/30
P ≈ 3507 watts
