What is an Atwood machine Why is it used for?
An Atwood Machine is a basic physics laboratory device often used to demonstrate basic principles of dynamics and acceleration. The machine typically involves a pulley, a string, and a system of masses.
What is the speed at which the lower right weight hits the floor?
COMPLETE ANSWER The lower right weight hits the floor at the speed v1=1.48 m⋅s−1.
How do Atwood machines work?
An Atwood’s Machine is a simple device consisting of a pulley, with two masses connected by a string that runs over the pulley. Each of the masses have two forces acting on it. Each has its own weight (m1g, or m2g) pointing downwards, and each has the tension (T) in the string pointing upwards.
How do you find velocity before hitting the ground?
Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s . Find the free fall distance using the equation s = (1/2)gt² = 0.5 * 9.80665 * 8² = 313.8 m .
How do you find speed before landing?
If you want to know the velocity of the object at some point before it hits the ground, use the distance the object has fallen at that point in place of the distance to the ground in either equation. Multiply feet per second by 0.68 to find the object’s velocity in miles per hour.
How does Newton’s second law apply to an Atwood machine?
Newton’s Second Law also states that the acceleration is inversely proportional to the mass. The acceleration of an object depends on the net applied force and the object’s mass. In an Atwood’s Machine, the difference in weight between two hanging masses determines the net force acting on the system of both masses.
Can a string have two different tensions?
This means the tension on both ends should be different, else force will be balanced. When an unbalanced torque acts the whole system accelerate and so does the rotation of the pulley. You may think that, it is impossible to have difference in magnitude of tension at two parts of the same string.

What is the mass of the Atwood pulley?
This is a common physics problem and it mentioned in several textbooks. 45. An Atwood machine (shown in figure below) consists of two masses, mA=65 kg and mB=75 kg, connected by a massless inelastic cord that passes over a pulley free to rotate, The pulley is a solid cylinder of radius R=0.45 m and mass 6 kg.
