Question #228205

A ball of mass 0.1kg is thrown vertically upwards with an initial velocity of 80m/s. Calculate the potential energy
1)halfway up
2)at its maximum height.
What is its kinetic energy as it leaves the ground??

Expert's answer

1)

"E_p'=0.5K=160\\ J"

2)

"E_p=K=320\\ J"

3)

"K=0.5(0.1)(80)^2=320\\ J"
