mass ‘m’ is projected vertically upwards with a speed ‘u’ and at the same instance another particle of mass ‘m’ is released from height ‘h’ vertically above the first particle. The two particles suffer a perfectly inelastic collision, and again reach a maximum height ‘h’ as one combined particle. What is the value of u?
