A child pulls a train of 2 cars with a horizontal force F of 10N .
Car1 has a mass of m1=3kg, and car2 has a mass of 1kg
The mass of the string connecting the the cars is small enough to be set equal to zero, and the friction can be neglected .
a- Find the normal force exerted on each car by the floor.
b- What is the tension force in the string
c- Find the acceleration of the train
well plz help me to solve and understand this problem
I can't figure out why the normal force in this problem is equal to the weight or how to find the acceleration.!! b]
