A particle moving in one dimension with a constant acceleration of 2m/s² is observed to cover a distance of 5 m during a particular interval of one second. The distance covered by the particle in the next one second interval is (in metres) :

a)5 , b)6, c)7(answer) , d)10 , e)12

How do you get this answer? Thanks!

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.
