A metal ball is dropped from a high platform and falls a distance of 40 m to the ground. The ball has a mass of 5.0 kg.
Neglecting air resistance, at what speed does the ball hit the ground? (Take g=9.8 m/s2g = 9.8\text{ m/s}^2g=9.8 m/s2)
20 m/s20\text{ m/s}20 m/s
28 m/s28\text{ m/s}28 m/s
40 m/s40\text{ m/s}40 m/s
200 m/s200\text{ m/s}200 m/s
