ISRO Mechanical Exam: Engineering Mechanics Quiz

Two blocks with masses M and m are in contact with each other and are resting on a horizontal frictionless floor. When horizontal force is applied to the heavier, the blocks accelerate to the right. The force between the two blocks are

Determine for the system in below Fig., when X, the downward displacement of the block, measured from the system’s equilibrium position, is used as the generalized coordinate. Take as the of the wheel.

Two objects P and Q are traveling horizontally with velocity of 8 m/sec and 6 m/s from left to right. They are separated by a distance of 15 m. The mass of the objects are 3 kg and 5 kg. If the coefficient of restitution is 0.7 what is the velocity (m/s) of P and Q after impact and when (seconds) and where (meters) will they impact with respect to initial positioning of Q. The corresponding answers are respectively.
