a physics question?
A child drags two boxes (112kg and 95.1kg) behind her bicycle as shown below. If she pulls the boxes with a force of 123 Newtons, what is the tension in the string that connects the boxes?

F(net) = F(applied)
(m₁+m₂)a = F(applied)
a = F(applied) /(m₁+m₂)
T = m₁a
T = m₁F(applied) /(m₁+m₂)
T = (95.1 kg)(123 N)/(95.1 kg + 112 kg)
T = 56.5 N

I would have to know string strength... Can be easily measured by a tension meter... or I can spend time pencil and paper... 1 hour...
