An experiment is set up using a hanging mass to pull a cart along a horizontal track. A light string is attached from the hanging mass over a pulley to a force sensor. A second light string is attached from the force sensor to the cart. There is a motion sensor that can be used to measure different features of the motion of the cart. The pulley is ideal, and there is negligible friction between the cart and the track. The cart of mass M starts at rest. The reading on the force sensor is F. Which of the following is a correct expression for the distance that the cart moved in timet? A Mt F B Ft M с Ft 2M D F42 2M E Mt2 2F Motion Sensor Cart Force Sensor 60 Hanging Mass
