46.6666 that is the mass number
Explanation:
14 divided 3.0
Answer:

Explanation:
The force of kinetic friction on the block is defined as:

Where
is the coefficient of kinetic friction between the block and the surface and N is the normal force, which is always perpendicular to the surface that the object contacts. So, according to the free body diagram of the block, we have:

Replacing this in the first equation and solving for
:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

Part b)

Part C)
This is loss in terms of thermal energy due to collision with the floor
Explanation:
Part a)
Since we know that the ball rises up by 65% of initial height
so after first bounce it will lose 35% of its initial energy
so we will have

Energy Loss = 0.35 mgH[/tex]


Part b)
Energy of the ball after first bounce

energy of ball after 2nd Bounce

energy of the ball after 3rd bounce



Now we will have energy loss in fourth bounce given as



Part C)
This is loss in terms of thermal energy due to collision with the floor
