Here in this tutorial we will study few pulley systems and solve some pulley tension problems as well.
newton’s second law
Impulse momentum theorem Impulse momentum theorem states that change of momentum of a body is equal to the impulse applied to it. Here Momentum is the product of mass and velocity of the body and we call it as the ‘Inertia to motion’ as well. And Impulse is produced when a considerable amount of force
Problem Statement A bullet of mass 50 g moving with an initial velocity of 100 m/s, strikes a wooden block and comes to rest after penetrating a distance 2 cm in it. Calculate: (i) Initial momentum of the bullet (ii)final momentum of the bullet (iii) retardation caused by the wooden block, and (iv) resistive force
Problem statement A force causes an acceleration of 10 m/s^2 in a body of mass 500 g. What acceleration would be caused by the same force in a body of mass 5 kg. Solution Case 1 mass = m=500 g = 0.5 kg Acceleration = a =10 m/s^2 Force = ma = 0.5 . 10
