a) Velocity V = \(\sqrt { 2gh} \) = \(\sqrt { 2( 3.7) ( 239) } \) = 42.05 m/s.
b) From H = \(\frac { gt^ 2} { 2} \), the time t = \(\sqrt { \frac { 2H} { g} } \) = \(\sqrt { \frac { 2( 239) } { ( 3.7) } } \) = 11.37 seconds.

A robot probe drops a camera off the rim of a \( 239 m \) high cliff on Mars, where the free-fall acceleration is \( - 3.7 m / s ^ { 2 } \) .
a) Find the velocity with which the camera hits the ground.
b) Find the time required for it to hit the ground.
