Question

The system is frictionless.If the person is moving at 8.3m/s then-

a) What is their total energy at A?
b)What is their speed at B?
c) if the end of the slide is 1.25m above the
surface of the water then how far away
from the end of the slide will they
hit the surface of the water ?​

Answer 1

Answer:

Explanation:

Diagram is unclear

Answer 2

The total energy of the person at point a is equal to the the total of the Kinetic and the potential energy of the person at the point

Explanation:

• . As the person reaches point be there is decrease in the potential energy. As a result of this there is increase in the kinetic energy.

• Based on this the speed can be calculated. the system is frictionless and as a result of this there is no loss of energy due to the presence of friction. there is always conservation of mechanical energy by the classical of physics.
