Answer:
The velocity is 7.0m/s
Explanation:
Given
Required
The bottom of the plane velocity
To do this, we apply the work-energy theorem which states that the energy at the highest point and at the lowest point are equal.
<u>At the highest point</u>
<u>At the lowest point</u>
Equate both values of energy
Take square roots of both sides
The velocity is 7.0m/s
