Answer:0.14kg
Step-by-step explanation:
the mass of the ball is 0.14kg becuse
you take the hieght of 85m nd muktiply to the force of gravity witch is 9.8 giving you 833.
you then take the jules of 116.62 and divide it by 833. giving you 0.14kg
Answer:0.14 kg
Gravitational potential energy=pe=116.62J
Height=h=85m
Acceleration due to gravity=g=9.8m/s^2
Mass=m
Pe=m x g x h
116.62=m x 9.8 x 85
116.62=m x 833
Divide both sides by 833
116.62 ➗ 833=(m x 833) ➗ 833
0.14=m
Mass=0.14 kg
