Answer:
The power output in horsepower to raise the object is, P = 13.14 Hp
Step-by-step explanation:
Given data,
The mass of the object, m = 2000 kg
The object is raised to a height, h = 5.0 m
The time duration of the work, t = 10 s
The force acting on the mass,
F = mg
= 2000 x 9.8
19600 N
The work done on the object is,
W = F x h
= 19600 x 5
= 98000 J
The rate of doing work is defined as the power. It is given by the formula,
P = W / t
= 98000 /10
= 9800 Watts
1 Hp = 745.7 Watts
Therefore,
9800 watts = 13.14 Hp
Hence, the power output in horsepower to raise the object is, P = 13.14 Hp
