Question

Rajan exerts a force of 250 N in pulling a cart at a constant speed of 30 m/s. Calculate the power exerted.​

Answer 1

Provided that:

• Force = 250 Newton
• Speed = 30 m/s

To calculate:

• The power exerted

Solution:

• The power = 7500 Watts

Using concept:

• Power formula

Using formula:

• P = F × v

Where, P denotes power, F denotes force and v denotes speed or velocity.

Required solution:

»»» Power = Force × Velocity

»»» P = Fv

»»» P = 250(30)

»»» P = 7500 Watts

»»» Power = 7500 Watts

_________________________

How power is the product of force and velocity!?

→ Power = Work/Time

→ Power = Force × Displacement/Time

→ Power = Force × Velocity

• Henceforth, derived! $\:$

Answer 2

Explanation:

★ Given :-

⠀⠀⠀⠀⠀⠀⠀⠀

• Force [ F ] = 250 N
• Speed [ S ] = 30 m/s

⠀⠀⠀⠀⠀⠀⠀⠀

★ To Find :-
