Why we take velocity of a moving body zero whenever body changes direction?......... Plz rply soon
1 Answer
Palash Agarwal
Velocity is a avector quantity, i.e. it depends o both direction and magnitude(amount). so for a partculaar direction, the velecity will be different than its speed, if it is moving in another direction. so, when a body cahnges its direction, the speed with respect to its previous direction is now no more. so we take it from zero for the next direction, as it has just started its journey towards that direction.

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

the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
