Explanation:
The mechanical energy must be saved because there is no friction. The maximum speed can be calculated using the equations of kinetic and gravitational potential energy.
Step-by-step explanation
Step 1.
When there is no friction, the sum of kinetic and potential energy is constant:
Where denotes mass, denotes velocity, denotes height, denotes gravity.
