A `30kg` box has to move up an inclined plane of slope `30^(@)` the horizontal with a unform velocity of `5 ms^(-1)`. If the frictional force retarding the motion is `150N`, the horizontal force required to move the box up is `(g =ms^(-2))` .

A 30 kg box has to move up an inclined slope of 30° to the horizontal at a uniform velocity of 5 ms^(-1) . If the frictional force retarding the motion is 150N, the horizontal force required to move up is ( g=10 ms^(-2) )

A 30 kg block is to be moved up an inclined plane at an anglue 30° to the horizontal with a velocity of 5ms^(-1) . If the frictional force retarding the motion is 150N find the horizontal force required to move the block up the plane. ( g=10ms^(-2) )
