A cart being pulled with 30N through a 2 m hallway over two seconds. How does it have the greatest power exerted on it

Power = 30 [watts]

Explanation:

Initia dа ta:

F = force = 30[N]

d = displacement = 2 [m]

By definition we know that work is equal to the product of force by the distance displaced

Therefore:

W = F * d = 30 * 2

W = 60 [J]

And power is defined as the amount of work done in a given time interval

time = t = 2 [sec]

Power = W / t

Power = 60 / 2

Power = 30 [W]
