Calculating Force of Friction: 36N Applied to 6kg Cart with 5.5m/s Acceleration

In summary, the problem involves a 6kg cart being accelerated at 5.5m/s2 with a force of 36N. We need to find the force of friction and use the formula F=ma to solve for it.

stupid forces of friction !

1. a force of 36N is applied to a 6kg cart. If the cart accelerates at 5.5m/s what is the force of fricrion



im not even sure what to do, I am in physics 20 and not very good at it please help this is my atempt



Ffriction=Fn*u idk what anthing means? haha please help ?

it dosent tell me a net force, i have no idea what to go. i tried f=umg but it didnt come out right i know the answear is 3 i just don't know how toget there

Find the net force using F=ma.
Try to go from there

Use F = ma. What should be F then? How will F get that value?
 

FAQ: Calculating Force of Friction: 36N Applied to 6kg Cart with 5.5m/s Acceleration

What causes friction?

Friction is caused by the resistance between two surfaces that are in contact with each other. This resistance is due to the microscopic irregularities on the surfaces that create a force opposing motion.

Why is friction considered a "stupid" force?

Friction is often considered a "stupid" force because it is not a force that is intentionally created or used. It is a natural phenomenon that can hinder the movement of objects and cause wear and tear.

How does friction affect motion?

Friction can affect motion by slowing it down or even stopping it completely. It can also change the direction of motion if the surfaces are not parallel, and can cause objects to heat up due to the energy generated from the friction force.

Can friction be beneficial?

Yes, friction can be beneficial in some cases. It allows us to walk without slipping, and it helps us grip objects. It is also important in many industrial processes, such as braking systems and polishing surfaces.

How can we reduce friction?

Friction can be reduced by using lubricants between surfaces, making surfaces smoother, or by using wheels or rollers to decrease surface contact. Reducing the weight of objects can also decrease the force of friction acting on them.
