2024 F = ma Exam — Question 16

A child of mass m holds onto the end of a massless rope of length ℓ, which is attached to a pivot a height H above the ground. The child is released from rest when the rope is straight and horizontal. m ℓ H d At some point, the child lets go of the rope, flies through the air, and lands on the ground a horizontal distance d from the pivot. On Earth, the maximum possible value of d is dE . If the setup is moved to the Moon, which has 1/6 the gravitational acceleration, what is the new maximum possible value of d?
