Question

Mass mA rests on a smooth horizontal surface, mB hangs vertically.

Part A

If mA=13.0 kg and mB=7.0 kg in the figure (Figure 1), determine the magnitude of the acceleration of each block.

Enter your answers numerically separated by a comma. Express your answers using two significant figures.

Explanation / Answer

using newton's law

Fnet = ma

a = Fnet/m

a = T - T + mBg / mA + mB

a = mBg / mA + mB  

a = 7*9.8 / 13 + 7

a = 3.43 m/s2
