- #1

- 5

- 0

This is what I have done so far. I summed up the forces on m1 and m2 separately:

#1 sumFym1=Fnormal-m1gcos30=0 (NOTE:I am using the inclined plane as my reference/x-axis, rather than the ground.)

#2 sumFxm1=T-Ffriction-m1gsin30=m1a

#3 sumFym2=T-m2g=-m2a

Fn=m1gcos30

Ffriction=.1Fn=.1m1gcos30

I substituted this value for Ffriction and then tried solving the system of equations by subtracting #3 from #2. The tension canceled out and I solved for acceleration. I got a=2.107cm/s^2. Using v^2=V0^2+2as, the velocity turned out to be 11.24cm/sec . My text book says the answer is supposed to be 83m/s. I am doing something wrong, but cannot figure out what. Any help would be appreciated.

Thanks!
