Block A in the figure (Figure 1) has a mass of 3.50kg , and block B has mass 12.0kg . The coefficient of kinetic friction between block B and the horizontal surface is 0.35.
A) What is the mass of block C if block B is moving to the right and speeding up with an acceleration 3.00m/s2 ?
B) What is the tension in each cord when block B has
this acceleration?
Homework Answers
frictional force between B and surface is
net force is given by
Ma = 3.5 kg
Mb =12.0 kg
a = 3.0 m/s2
plugging in and solving we get Mc = 17.94 kg
b) Tc = Mc(g-a) = 122N
Ta = Ma(a+g) = 44.8 N
