Explanation / Answer

on m2:

4.60 g - T2 = 4.60a ........(i)

on m1:

T1 = 2.60 a ..... (ii)

on pulley:

torque = I alpha

r (T2 - T1) = (m r^2 / 2) (a/r)

T2 - T1 = 0.265 a ..... (iii)

(i) + (ii) +(iii) =>

4.60 x 9.81 = (4.60 + 2.60 + 0.265) a

a = 6.045 m/s^2

1) a = 6.04 m/s^2

2) T1 = 2.60 a = 15.7 N

3) T2 = 4.60 ( g - a) = 17.3 N

4) d = v0 t + a t^2 /2

2.75 = 0 + 6.04 t^2 /2

t = 0.954 sec

5) v = v0 + a t = 6.04 x 0.954 = 5.76 m/s

w = v / r = 125.3 rad/s
