A student pushed a box 27.0 m across a smooth, horizontal floor using a constant force of 113 N. If the force was applied for 9.00 s, how much power was developed, to the nearest watt? Round your answer to the nearest whole number.

Respuesta :

339 Watts

Nm/s=Watts.
113N * 27m / 9s
339 Watts

The power is a dependent parameter on work done for a given interval of time. The magnitude of power developed due to the applied force is 339 W.

What is power?

The rate of doing work is known as Power. Mathematically, the power is equal to the ratio of work and time interval.

Given data -

The distance covered by the box is, d = 27.0 m.

The magnitude of the constant force is, F = 113 N.

The time interval for the application of force is, t = 9.00 s.

The expression for the power developed is given as,

P = W/t

here, W is the work done and its value is, W = F × d.

Solving as,

P = F × d/t

Solving as,

P = 113 × 27.0/9.0

P = 339 W

Thus, we can conclude that the magnitude of power developed due to the applied force is 339 W.
