Answer:
Explanation:
Given:
Force, f = 5 N
Velocity, v = 5 m/s
Power, p = energy/time
Energy = mass × acceleration × distance
Poer, p = force × velocity
= 5 × 5
= 25 W.
Note 1 watt = 0.00134 horsepower
But 25 watt,
0.00134 hp/1 watt × 25 watt
= 0.0335 hp.
Answer:
25 W
or
0.0335 hp
Explanation:
Power: This can be defined as the rate at which work is done. The S.I ubit of power is Watt(W).
The expression for Power in terms of force and velocity is given as,
P = F×V.................. Equation 1
Where P = Power, F = force of the electric motor, V = Velocity of electric motor
Given: F = 5 N, V = 5 m/s.
Substitute into equation 2
P = 5×5
P = 25 W.
P = 25 W
or
P = 25(0.00134) horse power
P = 0.0335 hp
Hence the motor produce a power of 25 W or 0.0335 hp
