It's a hanging mass problem where the block ontop of the surface is 3.2kg, and the hanging mass is 1.5kg

The coefficient of kinetic friction between the 3.2kg block and the surface is 0.30

You need to calculate acceleration

This is my bad drawing of the problem /lcRi3Ho

acceleration is measured in m/s/s (or m/s^2)

so ur wrong by a landslide

@Ice

you know when u write ur fnet statements

Fnet = ma

to get the right answer u had to do Fnet = -ma for the hanging mass

oh lol
I didn't look at the picture so :P
but technically Fnet=ma=mg=(-9.8m/s^2)x(Mass)
For pulleys, it will be easy to tell if + or - depending on direction of accelration
