Two particles having position vectors r1 = 3i + 5j m and r2 = -5i – 3j m are moving with velocities v1 = 4i + 3j m/s and v2 = ai + 7j m/s. If they collide after 2 seconds, the value of a is the value of a is Two particles having position [...]

A 10 kg object collides with a stationary 5 kg object and after collision they stick together and move forward with a velocity of 4 ms. What is the velocity with which the 10 kg object hits the second one ? The elastic energy stored in the spring in the equilibrium position of block is [...]

A particle of mass 0.1 kg moving with an initial speed v collides with another particle of same mass kept at rest. If after collision the total energy becomes 0.2 J, then: A particle of mass 0.1 kg moving with an initial speed v collides with another particle of same mass kept at rest. If [...]
