In a rope-climbing competition, all of the lifting is done by the arms; legs can only dangle. Imagine 220-lb Garvin Smith in training, hanging stationary from the rope, his legs off the floor. When prompted by his coach, he rapidly lifts his center of mass by 4 ft. in 0.65 s. Calculate Garvin Smith's acceleration. Round the final answer to one decimal place. Determine the net force (“force imbalance”) producing the acceleration. Round the final answer to one decimal place. Which forces are acting on Smith? (Note that his arms are part of himself, so they cannot exert a force on Smith.) With what magnitude force is Smith pulling down on the rope? Round the final answer to one decimal place. The force of 130.2 lb points _____.
