$g=-9.8\frac{m}{s^2}$

A rock is dropped from a helicopter hovering at above the ground. If the rock weighs , what is its kinetic energy right before it hits the ground?

A pendulum with string length is dropped from rest. If the mass at the end of the pendulum is , what is its maximum velocity?

$\small g=-9.8\frac{m}{s^2}$

Starting from rest a ball with a mass of 3kg experiences a constant force of 9N for 4s. Find the final kinetic energy (in joules) of the ball after 4s.
