Dimensional Formula for acceleration is

A body starts with a speed of 20 \(ms^{-1}\). Its speed is accelerated by \(2 ms^{-2}\). Find its velocity after 10 seconds.

Angular displacement in unit time is called as 

If  \(\alpha\) and \(\beta\) are two angles of projection for the same horizontal range for a projectile, then 

Maximum horizontal range of projectile \(R_{max}\) =

Which is the strongest force in nature?

Rocket propulsion is based on the principle of conservation of 

The normal force acting on a body kept on a flat surface is tripled. What will happen to the coefficient \(\mu\) of friction?

A rubber ball of mass \(M\) moving with speed \(u\) hits a hard surface. It rebounds with the same speed \(u\). The impulse imparted by the wall to the ball is
