               1. Which will cause a greater change in kinetic energy? changing its mass or changing
               its velocity? Why?

               2. A 50 g bullet moving with a velocity of 10 m/s strikes a block of mass 10 kg at rest
               and gets embedded in it. What is the loss in kinetic energy?

               1. A body of mass 5 kg that is initially at rest is subjected to a force that gives it an
                                      2
               acceleration of 4 m/s . The kinetic energy acquired by the body at the end of 10
               seconds is
               2. Find the amount of work required to stop a car of mass 1500 kg moving with a
               velocity of 60 km/h?

               3. Two masses of 1 gram and 4 gram are moving with same kinetic energies. Find the
               ratio of the magnitudes of their linear momentum?

               4. A body of mass 4 kg initially at rest is subject to a force 16 N. What is the kinetic
               energy acquired by the body at the end of 10 s?

               5. An object of mass m and velocity v has kinetic energy= 200J. Find the new kinetic
               energy if the mass of the object becomes double and velocity still remains the same?
