Here in this tutorial we will study few pulley systems and solve some pulley tension problems as well.

In this post, we will State and Prove the Impulse Momentum Theorem with the derivation of the equation. As evident, this theorem or principle is related to impulse and momentum. Hence a prior knowledge of these two will help.Related study links are provided here: Read about Momentum and here you can read about Impulse as […]

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 […]

Problem Statement A body of mass 500 g, initially at rest, is acted upon by a force which causes it to move a distance of 4 m in 2 sec. Calculate the force applied. Solution: mass=m = 500 g = 0.5 kg Initial velocity = u = 0 Distance travelled = s=4 m Time duration […]

Problem Statement A cricket ball of mass 100 g moving at a speed of 30 m/s is brought to rest by a player in 0.03 s. find the average force applied by the player. Solution: mass =m= 100 g = 100/1000 kg = 0.1 kg initial velocity = u=30 m/s Final velocity = v=0 Time […]

Problem Statement A force acts for 0.1 sec on a body of mass 2 kg initially at rest. The force is then withdrawn and the body moves with a velocity of 2 m/s. Find the magnitude of the force. Solution of class 9 Set1 Q12 Solution: A force acts on a body for 0.1 sec. […]

Problem Statement A force acts for 10 s on a stationary body of mass 100 kg after which the force ceases to act. The body moves through a distance of 100 m in the next 5 s. Calculate (i) the velocity acquired by the body, (ii) the acceleration produced by the force, and (iii) the […]

Newton’s Second Law states that the rate of change of momentum of a body is directly proportional to the net force applied on it, and this change in momentum takes place in the direction of the applied force. Mathematically it can be stated this way: F∝ (mV-mU)/t. Here, F is the net force acting on the […]
