Three objects are connected by light strings as shown in Figure P4.62. The string connecting the m1 = 6.00 kg mass and the m2 = 4.80 kg mass passes over a light frictionless pulley.(adsbygoogle = window.adsbygoogle || []).push({});

(b) Determine the tension in the two strings.

string between m2 and the 3.00 kg mass

I was able to do the first two part but this one is just troubling me and I am confuse. acceleration is 1.28 m/s^2

a = m2g + 3g - m1g / m1 + m2 + 3

and the tension between m1 and m2 is 66.48

T - m1g = m1a

but i cant seem to get m2 and the 3kg mass. this is what i tried

4.8(9.8) - 3(9.8) = 17.64 N

T - 17.64 = 7.8(1.28) = 27.624 which is incorrect. I dont know what im doing wrong or where to start.
