Apply newton s second law to the block on the left. As per this setup of the pulley in physics there is no movement of the cart along the y axis positive and negative of y axis and the cart only moves along the positive x axis.

But here i will try to explain a general and easier way to approach the problem.
Physics pulley problems. As a result pulley b and block 2 move together. A second ideal rope attaches pulley b to a second block of mass m 2. Hints and answers for pulley problems hint and answer for problem 2 this is called the atwood machine and is commonly used for demonstration in physics classes.
As part a of the drawing shows two blocks are connected by a rope that passes over a set of pulleys. The solution of this problem is divided into four parts. Home courses physics classical mechanics week 10.
Cart equations to solve pulley tension problems along y axis there is no net force so n w1 0. The goal of the problem is to calculate the accelerations of blocks 1 and 2. Now consider that the mass m 1 is moving down with acceleration a 1 and mass m 2 is moving up with acceleration a 2.
The rope and the pulleys are massless and there is no friction. For solving any pulley problem the first step is to understand the given conditions and write down the constraint equations accordingly. Ignore the masses of the pulley system and the rope.
We have mg t ma taking the downward direction as positive. Pulley problems also called atwood machine are the favorite problems to the professors and students seem to really struggle with it. As was stated in the description of the tension force to start out we use the simplest model which means we will assume that pulleys are massless and frictionless.
B find the magnitude of the tension of the string between m 1 and m2. Case 1 let m 1 m 2 be the mass attached to the pulley a. One of the favorite devices for physics problems is the pulley.
The bucket moves up and the block moves down. There are several ways to solve it and some of them are too complicated to understand. Set up the system of equations.
The block 1 has a weight of 400 n and the block 2 has a weight of 600 n. A bucket with mass m2 and a block with mass m1 are hung on a pulley system. Rotational motion 31 5 massive pulley problems 31 5 massive pulley problems course home.
Dynamics pulley problem 8. A find the magnitude of the acceleration of the 3 blocks. The hints and answers for these pulley problems will be given next.
C find the magnitude of the tension of the string between m2 and m3. Problem 5 the system below includes 3 blocks of masses m 1 1 kg m2 2 kg and m3 5 kg linked by massless and frictionless strings and pulleys. Find the magnitude of the acceleration with which the bucket and the block are moving and the magnitude of the tension force t by which the rope is stressed.
