Three dynamics carts have force sensors placed on top of them. Each force sensor is tied to a string that connects all three carts together. You use a sixth force sensor to pull the three dynamics carts forward. The reading on force sensor two is 3.3 N. Assume that the force sensors are light and there is negligable fricton acting on the carts.

a) What is the acceleration of all the carts?
b) What is the reading on each force sensor?
c) What force are you applying to force sensor six?
