A ball of mass m is tied to a string that is wrapped around the outside of a pulley. The pulley which is a uniform solid disk also has a mass m and the pulley rotates without friction about the axle t?

Why does a ball that is rolling come to a stop?
a round object rotates when there is a force acting tangentially.. in this case friction force is acting tangentially... so it should be rolling without stopping.. but it does stop since the weight is not balanced by its normal force(i.e. normal force and weight are not acting on the same point.)
Can you not walk without friction?
You require friction in order to walk.
What would be like to climb a rope without friction?
Without friction - climbing a rope would be impossible !
How friction help standing on a shower mat?
Without friction an object in motion would continue in motion unless acted upon by an outside force. Friction in this case is providing traction, so you can actually resist sliding. Shower mats increase friction, and reduce sliding. This friction is caused by physical imperfections within the two surfaces (feet & shower mat) when in contact with each other.
How does the friction force help people in walking?
Without friction it would be impossible to stand, you would instantly fall down flat. Without friction it would be impossible to crawl. Without friction the only way it would be possible to move would be by using thruster jets, as they do on spaceships.
Without friction what net force is needed to maintain a 1000 kg car in uniform motion for 30 minutes?
3kg
How do you improve torque and power transmitted without slipping using the uniform pressure theory and uniform wear theory?
the torque transmitting capacity according to uniform pressure theory is more than the uniform wear theory. but if you want to improve the torque transmitting capacity you have to increase the following parameters 1)coefficient of friction 2)number of friction and pressure plates 3)dimensions of the plates
Why is friction needed in the brakes?
Newton's First Law of Motion states: "An object in motion, remains in motion, unless acted upon by an outside force". Friction is an additional outside force that stops the motion of a vehicle faster. Without friction, the vehicle would never stop until it crashed into something.
Without friction there would be?
NO friction
When was Soldiers Without Uniform created?
Soldiers Without Uniform was created in 1942.
What is the duration of Soldiers Without Uniform?
The duration of Soldiers Without Uniform is 600.0 seconds.
Why does ice disappear on a car windowscreen even without the heater on?
the ice disappears/melts due to its friction with the air outside causing it to melt.

What police jobs can you do without wearing a uniform?
Unless the officers are on patrol, many of their duties can be performed without the uniform. Most prefer to wear the uniform.
Can you not walk without friction?

What is examples of friction?
The fact that you can walk without sliding is an example of friction.
