Free Fall

PHYS 101 week2-3

Passengers on the “Giant Drop”, a free-fall ride at Six Flags Great America sit in cars that are raised to the top of a tower. They are released for 2.6 s of free fall.• How fast are the

passengers moving after 2.6 s?

• If the cars in which they ride come to rest in a time of 1.0 s, what is the acceleration (magnitude and direction) experienced during this slowing-down phase of the ride?

A pole vaulter is nearly motionless as he clears the bar set at 5.2m above the ground. The top of the pad is 0.75m above the ground; It compresses by 0.50m as the pole vaulter comes to rest. • What is his

acceleration as he comes to rest on the pad?
