Answer:
The answer to your question is: Power = 58.86 W
Step-by-step explanation:
Power is defined as the rate at which energy is transferred of the rate at which work is done.
Power = P
Work = W
time = t
Data
mass = m = 5 kg
speed = v = constant
distance = 3 m
time = 2.5 s
gravity = g = 8.81 m/s²
Formula
Weight = mass x gravity
= m x g
Work = Weight x distance
Power = Work / time
Process
1.- Calculate the weight of the body
Weight = 5 x 9.81
Weight = 49.05 N
2.- Calculate the work done
Work = 49.05 x 3
Work = 147.15 J
3.- Calculate power
Power = 147.15 / 2.5
Power = 58.86 W
