A man of mass m speeds up while running ...

A man of mass `m` speeds up while running from rest to a speed v in a straight track along an inclined plane, after raising through a height `h`.
`W_(gravity)="work done by gravity on the man"`
`W_(friction)="work done by friction on the man"`
`W_(man)="work done by man"`
If in the previous problem, we replace the man by a block of mass m and release it from top of the inclined plane, and let it gain a speed v, then
