Five masses sliding across a frictionless surface as shown in
Five masses are sliding across a frictionless surface as shown in the above figure. Each mass is pushing the mass ahead of it. The masses are m1=11 kg, m2 = 11 kg, m3 = 8 kg, m4 = 7 kg, and m5 = 18 kg. The force acting on mass m1 is F = 247 N. What is the force with which mass m2 is acting on mass m3?
