Two objects of masses 200 and 400g are moving along the same line and direction with velocities of 4 metre per second and 2 metre per second respectively the line and after they collide and affir the collision the first object moves at a velocity of 1.6 metre per second determine the velocity ofthe second object
The speed of body of mass 4 kg increases from 2 metre per second to 4 metre per second in certain time interval find the increase in kinetic energy a body
What is the SI unit of energy? Define it.Calculate the kinetic energy of a body of mass 2 kg moving with a velocity of 0.1 metre per second. [5 MARKS]
An object of mass 1kg has a potential energy of 10J. What is the height of the object relative to the ground?(Takeg=10m/sec2)
