A car of mass 200 kg initially at rest on a boat of mass 1000 kg tied to the wall of dock, through a massless inextensible string. The car accelerates from rest to velocity 10 m/s in 2 sec. At t = 2 sec car applies brake and comes to rest relative to boat in negligible time. Neglecting friction between boat and water, the time at which boat will strike the wall is –

Sol. Velocity of boat after comes to rest: 
time taken by boat in hitting the wall
= 2 + 
= 8 sec.
