Laws of Motion ...

A particle of mass $$2$$ kg moving with a velocity of $$3$$ m/s is acted upon by a force which changes its direction of motion by an angle of $$90^o$$ without changing its speed. What is the magnitude of impulse experienced by the particle?

Three blocks A, B and C are suspended as shown below. mass of each of block A and B is m . if the system is in equilibrium , and mass of C is M then :  

A gun recoils after firing to conserve:

The momentum of a body of given mass is proportional to its:

Newton's third law:

A tennis ball and a cricket ball, both are stationary. To start motion in them:

An aircraft is moving with a velocity of $$300 \ ms^{-1}$$. If all the forces
acting on it are balanced, then 

Roads are banked on curves so that

Unit of momentum is:

The maximum velocity at the lowest point, so that the string just slack at the highest point in a vertical circle of radius l
