What kind of object have inertia?

Three concurrent forces F1, F2 and F3 are acting on a body. The body is said to be in equilibrium if:

A force of 100 N is applied on a body at rest. The body covers 10 m in 5 s due to this force. Mass of the body in kg is -

A motorboat of mass 200 kg is running on the surface of a river with the acceleration of 5 m/s2 and suddenly due to high waves in the water it decreases it’s acceleration to 1.5 m/s2. The force applied by the motor of the boat to do this is

A body of mass 20 kg is resting on a rough horizontal plane of the co-effcient of friction 0.5. If 40 N force is applied on a body then find the velocity of the body after 10 sec. (Take g = 10 m/sec2)

An object of mass 3 kg is at rest. Now a 6 N force is applied on the object for 3 seconds. Find the velocity of the object acquired by it in m / s.

The conservation of momentum is applicable in:

When a ball drops on the floor it bounces. This is according to

The property of an object at rest to stay at rest is understood as______.

Which force moves an aircraft through the air?
