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 block B strikes the floor and does not bounce.
Determine the velocity of block A, when it leaves the table
Options:
Answer:
B
Solution:
Until B hits the floor both blocks move together:
After B lands the string goes slack and A keeps this speed on the smooth table. Ans. (B)
