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

Step-by-step explanation:

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
