Respuesta :
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.
Answer:
63 Watt
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
