B. Accelerating a bowling ball from rest to 35 m/s
Explanation:
Accelerating a bowling ball from rest to 35m/s will require more impulse compared to a baseball.
Impulse is the force acting on a body a particular period of time. It is similar to momentum.
When impulse is applied on a body, it change it state from rest and cause motion.
A body with more mass will require a higher impulse to cause it to accelerate. Bowling balls are heavier. They require more impulse to make them move.

Answer:
Explanation:
mass of backpack, m = 8.1 kg
weight of climber, W = 656 N
height raised, h = 9.4 m
time, t = 28.2 min = 28.2 x 60 = 1692 second
weight of backpack, w = m x g = 8.1 x 9.8 = 79.38 N
Work done by the climber on the backpack = mg x h = 79.38 x 9.4 = 746.17 J
Wok done in lifting herself + backpack = (W + w) x h
= (656 + 79.38) x 9.4 = 6912.57 J
Power developed by the climber,P = Total work / time
P = 6912.57 / 1692 = 4.09 W
