Question
A truck of mass
30
,
000
kg moves up an inclined plane of slope
1
in
100
at a speed of
30
kmph. The power of the truck is (given g = 10
ms-l)

Solution
As truck is moving on an incline plane therefore only component of weight
(
m
g
sin
θ
)
will oppose the upward motion
Power = force × velocity
