Question

In the figure, three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T3 = 73.9 N. If m1 = 10.6 kg, m2 = 26.6 kg, and m3 = 36.8 kg, calculate (a) the magnitude of the system's acceleration, (b) the tension T1, and (c) the tension T2.

In the figure, three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T3 = 73.9 N. If m1 = 10.6 kg, m2 = 26.6 kg, and m3 = 36.8 kg, calculate (a) the magnitude of the system's acceleration, (b) the tension T1, and (c) the tension T2.

Explanation / Answer

a)a = Fnet/(m1+m2+m3) = 1 m/s^2

b) T = 73.9 - (m2+m3)*a = 73.9 - (26.6+36.8)*1 = 10.5 N

c) T = 73.9 - m3 = 73.9 - 36.8 = 37.1 N
