A parachutist with a camera, both descending at a speed of 13 m/s, releases the camera
at an altitude of 57.8 m.
What is the magitude of the velocity of the
camera just before it hits the ground? The
acceleration of gravity is 9.8 m/s
2
and air
friction is negligible.
Answer in units of m/s

How long does it take the camera to reach the
ground?
Answer in units of s
