Answer:
Explanation:
Mass of ball = 3.0102 Kg.Explanation:Potential energy at height h is given byPE = mgh where m is the mass of the bodyg is the the acceleration due to gravity whose value is 9.8 m/s^2h is the height from surface levelPE is potential energyIn the problem given h = 2 metersPE = 59 joules59 = m*9.8*2=> m = 59/9.8*2 = 3.0102 KgThus, mass of ball is 3.0102 Kg.
