1.	Figure shows the velocity-time graph for two masses `R` and `S` that collided elastically. Which of the following statements is true? i. `R` and `S` moved in the same direction after the collision. ii. The velocities of `R` and `S` were equal at the mid time of the collision. iii. The mass of `R` was greater than mass of `S`. Which of the following is true?A. I onlyB. II onlyC. I and II onlyD. I, II and III
Answer» Correct Answer - D `COLM : m_(R ) (0.8) + m_(R ) (0.2) + m_(S)(1.0)` `rArr 0.6 m_(R ) = m_(S) rArr m_(R ) gt m_(S)`

Two blocks `A` and `B` are joined by means of a slacked string passing over a massless pulley as shown in Figure. The system is released from rest and it becomes taut when `B` falls a distance `0.5 m`. a. Find the common velocity of the two blocks just after the string becomes taut. b. Find the magnitude of impulse on the pulley by the clamp during the small interval while string becomes taut.
A body of mass `1 kg` moving with velocity `1 m//s` makes an elastic one dimesional collision with an identical stationary body. They are in contact for brief time `1 sec`. Their force of interaction increases form zero to `F_(0)` linearly in time `0.5s` and decreases linearly to zero in further time `0.5 sec` as shown in figure. Find the magnitude of force `F_(0)` in newton.
