141693 A car accelerates from rest with acceleration \(1.2 \mathrm{~m} / \mathrm{s}^{2}\). A bus moves with constant speed of 12 \(\mathrm{m} / \mathrm{s}\) in a parallel lane. How long does the car take from its start to meet the bus?

141694 A ball of mass \(10 \mathrm{~kg}\) is moving with a velocity of \(10 \mathrm{~m} / \mathrm{s}\). It strikes another ball of mass \(5 \mathrm{~kg}\), which is moving in the same direction with a velocity of \(4 \mathrm{~m} / \mathrm{s}\). If the collision is elastic their velocities after collision will be respectively:

141695 A man is \(45 \mathrm{~m}\) behind the bus when the bus start accelerating from rest with acceleration \(2.5 \mathrm{~m} / \mathrm{s}^{2}\). With what minimum velocity should the man start running to catch the bus?

141655 Given below are the velocity-time graphs of five particles, A,B,C,D and E. The correct graph from the following \(v\)-t plots in which the velocity of the particle is function of \(t^{2}\) is
