meter-high building

From the top of a 70-meter-high building, a l-kilogram ball is thrown directly downward with an initial speed of
10 meters per second. If the ball reaches the ground with a speed of 30 meters per second, the energy lost to
friction is most nearly (A) 0J (B) 100 J (C) 300 J ( D) 400 J (E) 700 J
56. A pendulum consists of a ball of mass m suspended at the end of a
massless cord of length L as shown. The pendulum is drawn aside
through an angle of 60° with the vertical and released. At the low point
of its swing, the speed of the pendulum ball is
