The ball A collides elastically with an identical ball B with a speed v. The ball B touches another identical ball C.The velocity of C,after the impact,is equal to
a.v
b.v/2
c.v/4
d.none of these
Approved Tutor Answer14 Years agothe velocity of c is v because the masses of the three balls are same , therefore the the velocities are transfered . so the correct option is A
Approved Tutor Answer14 Years agoThe answer is v (a.)
Solution: When a body collides elastically with an another body, the two intechanges their velocities.
In this case body A moving with velocity v collides with an another body B at rest , as such after the collison the two balls interchange their velocites and B starts moving with velocity v and A comes to rest.
Similar case happens when body B collides with body C. The two interchange their velocites and C began to move with a velocity equal to v and body B comes to rest
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.
