A parachutist with a camera, both descending at a speed of 9.2 m/s, releases the camera
at an altitude of 32.3 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.
How long does it take the camera to reach the
ground?

V^2=u^2+2as. v= the final velocity; u=the initial velocity (9.2 m/s; a is accel and s is distance (more accutately, displacement). Solve for v.
