Two identical carts constrained to move ...

Two identical carts constrained to move on a straight line, on which sit two twins of same mass, are moving with equal velocity. At some time snow begins to drop uniformly. Ram, sitting on one of the carts, picks the snow from cart and throws off the falling snow sideways and in the second cart Shyam is asleep.

A

Cart carrying Ram will have more speed finally than that carrying Shyam.

B

Cart carrying Ram will have less speed finally than that carrying Shyam.

C

Cart carrying Ram will have same speed finally than that carrying Shyam.

D

depends on the amount of snow thrown.

Text Solution

Verified by Experts

The correct Answer is:
D
`mv_(0)=(m+m')v` where `m'` is mass of snow that is added.
`v'=(mv_(0))(m+m')`
since Ram throw sideways, no impulse acts in the direction of motion.
`v'` for Ram and Shayam are equal.

Study the following information carefully and answer the questions given below: 9 people are sitting in a straight line and some of them are facing north while some of them are facing south. The distance between any two immediate neighbours is the same. All the given information is not necessarily in the same order. P sits second from one of the extreme ends of the line. R sits third to the right of P. Two people sit between R and S. U sits second to the right of S. Immediate neighbours of S face a direction opposite to that of S. Immediate neighbours of U face opposite directions. T sits second to the right of U. Both U and T face the same direction. W is a neighbour of T. W and T face opposite directions. Persons sitting at extreme ends face opposite directions. Q sits second to the left of V. X does not face south. Who among the following sit at the extreme ends?
