Rey lifts a 6,300 g metal ball from the ground to a height of 98.15 cm close to his body. (a) What is the balls PEg? Realizing that the ball is heavy, he suddenly releases it with a speed of 15m/sa. (b) what is the balls KE?
Given:
m= 6,300 g =6.3 kg
h= 98.15 cm =0.9815 m
Formula:
a) PE= mgh
PE=
PE=
[v= 15 m/s]
b) KE= mv²/2
KE=
KE=
