Passage / Comprehension

Two small blocks, each of mass m, are connected by a string of constant length 4h and negligible mass. Block A is placed on a smooth table top, and block B hangs over the edge of the table. The table top is at a distance 2h above the floor. Block B is released from rest at a distance h above the floor at t = 0. At time $t_{0}$ block B strikes the floor and does not bounce.

Determine the distance between the landing points of the two blocks

Options:

Answer:

Solution:

A leaves the table 2h above the floor at $g h$ :

$t = \frac{2 \times 2 h}{g}, x = g h \times 2 \frac{h}{g} = 2 h$

B landed directly below the edge, so the landing points are 2h apart. Ans. (B)
