Question

Carter pushes a bag full of basketball jerseys across the gym floor. The he pushes with a constant force of 21 newtons. If he pushes the bag 9 meters in 3 seconds, how much power does he use?

Answer 1

63 Watt

Step-by-step explanation:

F = 21 N, s = 9 m, t = 3 s

Work done in pushing the bag, W = force x distance

W = 21 x 9 = 189 J

Power = work / time

P = 189 / 3 = 63 Watt

Answer 2

Carter needs a power equal to 63 W to be able to push the bag full of Jersey. This is by using the formula: Power is equal to the product of Force applied and Displacement all over time traveled.
