A Mass of mass 40 kg in standing on a uniform planck of mass 60 kg lying on horizontal frictionless ice. The man walks from one end to the other end of the plank. The distance walked by the man relative to ice (given length of plank = 5 m)

View answer and explanation

Correct option: B

3 m

Option B is correct. Using the concept that the center of mass of the man-plank system remains constant, the distance walked by the man relative to the ice is calculated to be 3 m.
