A 60 g golf ball is dropped from a level of 2 m high. It rebounds to 1.5 m. How much energy is lost? Group of answer choices 0.5
1 answer:
Answer: A 60 g golf ball is dropped from a level of 2 m high. It rebounds to 1.5 m. Energy loss will be 0.29J
Explanation: To find the correct answer, we have to know more about the Gravitational potential energy.
<h3>What is gravitational potential energy?</h3>- The energy possessed by a body by virtue of its position in gravitational field of earth is called gravitational potential energy.
- The gravitational potential energy of a body at a height h with respect to the height h will be,
- Expression for gravitational potential energy loss will be,
- The total energy before the ball dropped will be,
- The total energy after when the ball rebounds to 1.5m will be,
- The total energy loss will be,
Thus, we can conclude that, the energy loss will be,0.294J.

The percent difference between two numbers and
is given by
The absolute value is there because we only care about the absolute percent difference, and not taking into account whether we go from to
or vice versa. If we remove them, we have two possible interpretations of percent difference.
For example, the (absolute) percent difference between 3 and 6 is
In other words, we add 100% of 3 to 3 to end up with 6. This is the same as the percent difference going from 3 to 6. On the other hand, the percent difference going from 6 to 3 is
which is to say, we take away 50% of 6 away from 6 to end up with 3.
"Make comparisons to object measurements" tells us that the differences should be computed relative to "measurements for object". In other words, take from the left column and
from the right column.
