You must know something else or there is not enough info. Did you time it until the suspended mass hit the floor? Or did the top mass stop before it reached the pulley and you measured how far it travelled in total?SSJBLOOD said:
Then you can calculate the acceleration.SSJBLOOD said:
To find the coefficient of friction with masses given, you first need to calculate the net force acting on the object by using the equation Fnet = ma, where Fnet is the net force, m is the mass of the object, and a is the acceleration. Then, use the equation Ffriction = μ * Fn, where Ffriction is the force of friction, μ is the coefficient of friction, and Fn is the normal force. Finally, solve for μ by rearranging the equation to μ = Ffriction / Fn.
To find the acceleration with masses given, you can use the equation Fnet = ma, where Fnet is the net force acting on the object, m is the total mass of the object (including any additional masses), and a is the acceleration. Rearrange the equation to solve for acceleration by dividing the net force by the total mass of the object.
The coefficient of friction is a unitless quantity, as it is a ratio of the force of friction to the normal force. Therefore, it does not have any specific units associated with it.
Yes, the coefficient of friction can be greater than 1. A coefficient of friction greater than 1 indicates that the force of friction is greater than the normal force acting on the object, resulting in a higher resistance to motion.
The coefficient of friction affects the acceleration of an object by determining the amount of frictional force opposing the motion of the object. A higher coefficient of friction will result in a greater force of friction, which in turn will reduce the acceleration of the object. Conversely, a lower coefficient of friction will result in less frictional force and a higher acceleration for the object.
