(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A block of mass m1 on a rough horizontal surface is connected to a ball of mass m2 by a lightweight cord over a lightweight frictionless pulley as shown. A force of magnitude F at an angle theta with the horizontal is applied to the block. The coefficient of friction between the block and surface is [tex]\mu_k[/tex]

a.) draw a free body diagram of the 2 masses

b.) use newton's dynamic equation to determine the magnitude of the acceleration of theh 2 objects in terms of their masses, F, theta, and [tex]\mu_k[/tex]

c.) what is the tension in the cord

2. Relevant equations

F= ma

Ffk= uk* Fn

and a newton's dynamic equation? ==> what is that exactly??

3. The attempt at a solution

a)for the free body diagram

b) how would I do this question...not sure and I'm stuck after the free body diagram...hm..

c) I guess I would need to solve part b to get part c

~I do know that they both have the same accelration but how would I know if the total forces [tex]\sum Fx= 0[/tex]?

I need help please..
