How to Calculate Kinetic Friction: 2 kg Block on Steel Table | Homework Help

AI Thread Summary
To calculate the speed of a 2 kg steel block being pulled by a 16 N tension on a steel table, the coefficient of kinetic friction is 0.600. The frictional force can be determined using the equation Fk = μk * mg, where mg is the weight of the block. The net force acting on the block is the tension minus the frictional force. This net force allows for the calculation of acceleration using F = ma. Finally, the acceleration can be used to find the block's speed after moving 1.30 m.

Homework Statement



A 2.00 kg steel block is at rest on a steel table. A horizontal string pulls on the block. The coefficient of kinetic friction of dry steel on steel is μk=.600

If the string tension is 16.0 N, what is the block's speed after moving 1.30 m?

Welcome to PF.

How would you think to solve it?
 
well i know that Fk = μkmg and f=ma

im just not sure what the force should be and if it will give me the right acceleration

Well what is the frictional resistance?

What force is applied by the string?

What is the net force then?

With the mass you have the acceleration.

And with acceleration you can figure the speed.
 
net force = tension force of the rope - frictional force?
 
got it! thanks for the tips

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
