Two projectiles ‘A’ and ‘B’ are thrown with same speed but at angle of 40 degree and 50 degree with the horizontal. The horizontal range of ‘A’ will be:
A body moves a distance of 10 m along a straight line under the action of a force of 5 N. If the work done is 25
joules, the angle which the force makes with the direction of motion of the body is?
Initially, four identical uniform blocks, each of mass m and thickness h, are spread on a table
How much work is done on the blocks in stacking them on top of one another?
