no friction, so why is gravity involved?
f = m a
89 = (8 + 33 + 49) a
Three blocks are located on a horizontal frictionless table. They are connected by a massless cord, as shown in the figure, and pulled to the right. The masses of the three blocks are m1 = 8 kg, m2 = 33 kg, and m3 = 49 kg. The pulling force is equal to T3 = 89 N. What is the acceleration of the system?
I know the equation is m(a+g). I keep getting the wrong answer. Help!
