Halliday, Resnick & Walker β Potential Energy and Conservation of Energy: Problem 128
Ball shot into sand. A steel ball with mass \( m = 5.2 \text{ g} \) is fired vertically downward from a height \( h_1 \) of \( 18 \text{ m} \) with an initial speed \( v_0 \) of \( 14 \text{ m/s} \). It buries itself in sand to a depth \( h_2 \) of \( 21 \text{ cm} \). (a) What is the change in the mechanical energy of the ball? (b) What is the change in the internal energy of the ballβEarthβsand system? (c) What is the magnitude \( F_{\text{avg}} \) of the average force on the ball from the sand?
