How much is the work done in pulling up a block of wood weighing 2KN for a length of 10m on a smooth plane inclined at an angle of 30° with the horizontal ?
A force of 7N, making an angle θ with the horizontal, acting on an object displaces it by 0.5m along the horizontal direction. If the object gains K.E. of 2J, what is the horizontal component of the force?
A 60 kg JATAN with 10 kg load on his head climbs 25 steps of 0.20m height each. What is the work done in climbing? (g = 10 m/s2)
A ball of mass 5 kg is striding on a plane with initial velocity of 10 m/s. If co-efficient of friction between surface and ball is (1/2), then before stopping it will describe ……. (g = 10 m/s2)
