A block of ,mass m =11.7 kg is to be pushed a distance of s=4.65 m. Assuming frictionless surface. Calculate the work done in applying a force parallel to the incline to push the block up at a constant speed. (Take, g=9.8 `ms^(-2)`)

An inclined plane is moving with Constant velocity v = 4 m//s on a horizoontal surface as shown in figure. If a block of mass 2 kg is kept at top of the incline and their is no friction between the block and the incline, then the distance travelled by the incline till the block reaches bottom of the inclined is (g = 10 m//s^(2))
