Answer:

B)154 J

Step-by-step explanation:

Mass of bowling ball=m=6.55kg

Height of bowling ball from ground=h=2.4m

Acceleration due to gravity=
g=9.8m/s^2

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=
6.55* 2.4* 9.8=154J

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