dear pallavi
let t time is taken for overtake,and x is the total distance to overtake.
distance travelled by blue car in t sex is (x-5)m
distance travelled by red car in t sex is (x+5)m
t=(x-5)*1000/42 =(x+5)*1000/60........(1)
or (x-5)/42=(x+5)/60
calculate x from here. this is the required distance.
and put this value in eq (1) and calculate t .

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.
