## Homework Statement

A 3kg load on an inclined plane of angel 30 degrees is connected by a cord over a frictionless pulley to a second load which has a mass of 2 kg. Find the:

a) Acceleration of each load

b) tension of each chord

## Homework Equations

none?

## The Attempt at a Solution

__block A / box on inclined plane__

[tex]\sum[/tex]F

_{y}= 0

-W

_{y}cos30[tex]\circ[/tex] + N

_{F}= 0

-30cos30 + N

_{F}= 0

-25.98 + N

_{F}= 0

-25.98 = N

_{F}

**N**

_{F}= 25.98*f*=[tex]\mu[/tex] N

_{F}

*f*= 0.3 (25.98)

*f*= 7.794[tex]\sum[/tex]F

_{x}= ma

W

_{x}sin30[tex]\circ[/tex] - T - f = ma

15 - T - 7.794 = ma

15 - 7.794 - T = (3)(a)

-T = 3a - 7.206

**T = 7.206 - 3a**

__block b__

[tex]\sum[/tex]F

_{x}= ma

T-W = ma

T - (2)(10) = (2)a

T - 20 = 2a

**T= 2a+20**

T=T

2a+20 = 7.206 - 3a

2a+3a = 7.206 - 20

5a = -12.794

a = - 2.56 m/s

^{2}

T

_{1}=7.206 - 3a

T= 7.206- 3(-2.56)

T= 14.886 N

T

_{2}= 2a+20

T= 2(-2.56) + 20

T= -3.1176 N

T

_{2}+T

_{1}= Total

_{T}

14.886 + (-3.1176) = Total

_{T}

Total

_{T}= 11.7684 N

I'm not sure if I got the right answer :( someone help?
