The KE acquired by a mass m in traveling a certain distance d, starting from rest, under the action of a constant force is directly proportional to  

If the momentum of a body is increased by 150% then the percentage increase in its kinetic energy is

A particle of mass m₁ is moving with a velocity v₁ and another particle of mass m₂ is moving with a velocity v₂. Both of them have the same momentum but their different kinetic energies are E₁ and E₂ respectively. If m₁> m₂, then

Two equal masses m₁ and m₂ moving along the same straight line with velocities +03 m/s and -5 m/s respectively collide elastically. There velocities after the collision will be respectively

A force acts on a 3.0 g particle in such a way that the position of the particle as a function of time is given by  x = 3 t – 4 t ² +  t ^3, where x is in meter and  t  in second. The work done during the first 4 s is 

300 J of work is done in sliding a 2kg block up an inclined plane of height 10 m. Taking g = 10 m/s², work done against friction is

If kinetic energy of a body is increased by 300% then the percentage change in momentum will be

 Water falls from a height of 60 m at the rate of 15kg/s to operate a turbine. The losses due to frictional forces are 10% of energy. How much power is generated by the turbine?   (Take g = 10 m/s²)  

The identical balls A and B moving with velocities + 0.5 m/s and -0.3 m/s respectively collide head on elastically. The velocity of the balls A and B after collision will be respectively

An engine pumps water continuously through a hose. Water leaves the hose with a velocity v and m is the mass per unit length of water jet. What is the rate at which kinetic energy is imparted to water?
