Center Of Mass
The mass per unit length of a non - uniform rod of length L is given μ=λx2 , where λ is a constant and x is distance from one end of the rod. The distance of the center of mas of rod from this end is

A particle of mass m moving with horizontal speed 6m/s as shown in the figure. If m<<M then for one - dimensional elastic collision , the speed of lighter particle after collision will be
A block of mass m is pushed towards the movable wedge of mass M and height h, with a velocity v0. All surfaces are smooth . The minimum value of v0 for which the block will reach the top of the wedge is
A ball A of mass 1kg , moving with a speed of 12m/s , collides obliquely and elasticity with another ball B which was initially at rest. Ball A then moves off at the right angle to its initial direction with a speed of 5m/s. The momentum of ball B after the collision is
