A6.55 kg bowling ball is lifted 2.40 m into a storage rack. calculate the increase in the ball's potential energy a) 152 j b) 154 j c) 156 j d) 158j e) none of these

B)154 J

Explanation:

Mass of bowling ball=m=6.55kg

Height of bowling ball from ground=h=2.4m

Acceleration due to gravity=

We know that

Potential energy=mgh

Where m=Mass of object

g=Acceleration due to gravity

h=Height of object from ground

Substitute the values then we get

Potential energy=

Hence, the increase in the ball's potential energy=154J

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
