mass = 64g = 0.064speed = 20m/s Kinetic Energy = 1/2 mv*v
0.5* 0.064*20*20
12.8 JAssuming that there is no loss of energy the kinetic energy
at ground will change into potential energy at the highest point according
ti the law of conservation of energy Potential Energy = 12.8J Posted at: Thu Jan 6 06:20:50 2011 (GMT) |
