1) A steel ball of mass 5.2 g is fired vertically DOWNWARD from a height hof 18 m with an initial speed v0 of 14 m/s into a sandbed. It buries itself to a depth of 21 cm in the sand on impact. a) What is the work done by the sand on the steel ball? b) What was the average force exerted by the sand on the ball?
