A block of mass m1 = 4.00 kg on a frictionless inclined plane of angle 30.0° is connected by a cord over a massless, frictionless pulley to a second block of mass m2 = 2.40 kg hanging vertically (Fig. 5-41).
Figure 5-41
(a) What is the magnitude of the acceleration of each block?
F=ma; F1=M1g F1 = 23.5N F2=M2Gsin(30)=19.6N Ax1=3.9N/4kg=.975m/s^2 that's wrong, the same for the other mass which I just subbed the 4 with the 2.4kg
(b)What is the tension in the cord?
the two forces combined 19.6+23.5=43.12N
also wrong
