Question

Two blocks of masses 2 kg and 3 kg are connected by string of length 1m. At any instant the velocities of block of mass 2 kg and 3 kg are 5 m/s in opposite direction and perpendicular to the length of string. (assume gravity free space)

Answer 1

Two blocks of masses 2kg and 3kg are connected by string of length 1m. At any instant the velocities of block of mass 2kg and 3kg is 5m/s in opposite direction and perpendicular to the lenght of string ad is also parallel to the horizontal table.                                                                                                       (A) Tension in the string is 110 N                                                                                                                                               (B) Tension in the string is 120 N                                                                                                                                               (C) Velocity of centre of mass is 2m/s                                                                                                                                       (D) Velocity of centre of mass is 5 m/s
