A body moving in positive x direction can it have an acceleration in negetive x direction?which quantity tells the direction of motion?
Yes,
It can have the acceleration in negetive x direction if the velocity of the body is decreasing without changing the direction of motion.
But at an instant the direction of acceleration has nothing to do with the direction of motion.
This is the instantaneous velocity that tells the direction of motion at any instant.Instantaneous velocity is defined as dv/dt.
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.
