For the car with 60kmph to overtake the first car it should travel a relative distance of 10 m
(5m for catching up and 5m for getting clear ahead)
therefore Srel = 10 m
Vrel = 60-42 = 18km/hr = 5 m/s
Relative acceleration = 0 .since both are moving with constant velocities.
Now using relative motion, S = Vrel × t
therefore time ,t = S / Vrel = 10/5 = 2s
Distance is 60 × 5/18 × 2 = 100/3 = 33.33 m
hence total road distance used for overtake = 5 + 33.33 = 38.33 m
Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
