A dynamics cart sits on a lab desk has a mass of 900 g. It is connected to a suspended 500 g mass by a string that is threaded through a frictionless pulley. The coefficient of friction between the lab desk and the dynamics cart is 0.25.
a) Determine the acceleration of the dynamics cart when the 500 g mass is released (Include FBD’s).
b) If the dynamics cart takes 1.3 s to reach the pulley, what distance does it travel?
