2 kg steel block pulled on steel table with 16 N tension

[ceday]

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 μ_k=.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?

 

[ceday]

well i know that F_k = μ_kmg 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.

 

[ceday]

net force = tension force of the rope - frictional force?

got it! thanks for the tips
