**1. A block with mass m**by a massless cord passing over a small frictionless pulley. The coefficient of kinectic freiction between mass m

_{1}is placed on an inclined plane with slope angle α and is connected to a second hinging block with mass m_{2}> m_{1}_{a}and the incline is negligible. Find:

(a) the acceleration vector of mass m

_{1}

(b) the acceleration vector of mass m

_{2}

(c) the magnitude of the normal force on mass m

_{1}

(d) the magnitude of the tension in the cord

Newton's Equations

## The Attempt at a Solution

(a.) Drawing a FBD diagram for mass 1 gives that the sum of the forces for the x-component F

_{x}= T - wsinα.

F

_{y}= n - wcosα.

Since there is no acceleration in the y-direction, the only acceleration we need to worry about is that for the x-component.

ƩF

_{x}= m

_{1}a

m

_{1}a = T - wsinα

a = (T - wsinα)/m

_{1}

a = (T - m

_{1}gsinα)/m

_{1}?

I am not sure if this is correct or wrong. Please help me out here
