Answer:
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
<span>It does not matter how heavy the object is, as long as there is no drag or wind interference (such as wind on a feather or piece of paper) the gravitational pull will be equal, therefore the answer is 9s.</span>
