Contact us: [email protected]. April 7, The second law relates force to acceleration when the net force is not zero. Third law: The third law is a relation between the forces that two interacting bodies exert on each other.

Experiments show that whenever two bodies interact, the two forces they exert on each other are always equal in magnitude and opposite in direction. For example, when you hit your fist on a wall you feel some pain because the wall pushes back on your fist. This is because the concrete slab pushes back on you with a force equal to your weight. The two opposite forces referred to in the preceding examples are sometimes called an action — reaction pair.

The action and reaction forces each act on two separate bodies. For instance the action force of your fist acts on the wall while the reaction force of the wall acts on your fist. Two forces have the same magnitude A. What is the angle between the two forces if their sum has a magnitude of a. Two boys pull horizontally on ropes attached to a post and the angle between the ropes is 60 degrees.

If the force from boy A is N and that from boy B is N. Find the magnitude and direction of the resultant force. A man applies a constant horizontal force of N to a block of wood on a smooth horizontal floor. The block starts from rest and moves 12 m in 5 seconds. What is the mass of the block? If the man stops pushing at the end of 5s, how far does the block move in the next 5 seconds? A passenger in a lift experiences an upward normal force of N.

If the weight of the man is N, find his acceleration. A loaded elevator has a total mass of kg and the cables can withstand a maximum tension of 28, N. What is the maximum upward acceleration for the elevator if the cables are not to break? If the mass of the bullet is 1.

In what time does the bullet come to rest?
