Here in this tutorial we will study few pulley systems and solve some pulley tension problems as well.
Impulse momentum theorem states that the change of momentum of a body is equal to the impulse applied to it. Mathematically, its represented with this equation: Δp = F . Δt Here, Δp = change in momentum. And F . Δt is the impulse applied. Impulse is represented as the product of Applied force F […]
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 […]
