Question

state newton's first law of motion. Show that Newton's first law of motion is a special case of Newton's second law. Determine the acceleration of a car of mass800 kg, on application of a force of 200 newton on it

Answer 1

the body which is at rest will remain at reat and a body which is in motion will remain in motion unless and until u apply an external force

Answer 2

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.....
When net force becomes zero.. i. e. F=0 implies... Ma=0 but M is not equal to zero... Therefore a=0...... Hence, it is a spcl case of newtons second law....
Acceleration =0.25 m/s ^2
