    1.A railway wagon (A) of mass 10000 Kg collides with another identical wagon (B) as shown in Figure 1. If A is moving at 5 m/s and B is at rest at the time of collision, calculate maximum compression in spring S with a spring constant 20 MN/m.

    2.Three perfectly elastic balls A, B, and C of masses 2 Kg, 4 Kg, and 8 Kg, respectively move along the same straight line and in the same reaction with velocities of 4 m/s,
    1 m/s, and 0.75 m/s. The ball A collides with ball B and subsequently the ball B impinges with ball C. Make calculations to show that the balls B and C will be brought to rest after the impacts

    3.A cannon ball fired from the ground attained a maximum height of 1 km. At this maximum height, the radius of curvature of its path was also equal to 1 Km. With this data determine the initial velocity and angle of projection from the ground. Neglect air resistance

    4 A flat road has a curve segment with a radius of 100 m. While negotiating this curve, a vehicle slipped on its tyres as well as tried to roll over at a particular speed. Calculate this speed assuming a friction co-efficient of 0.5. Also calculate the height of CG of the vehicle above ground if distance between the tyres at the front or rear is 1.2 m

    We will not do your homework for you. Please show your work, and tell us where you are stuck.
