Cart Hanger Students attach a light string to a cart. The string passes over an ideal pulley to a hanger. A number of small identical plates are on both the cart and the hanger. The students measure the acceleration of the cart when the cart-hanger- plate system is released from rest. The students repeat this procedure for several trials. For each trial, students move one plate from the cart onto the hanger. The data are collected and shown in the straight-line graph. Which quantities on the vertical and horizontal axis, respectively, could produce the graph shown?Vertical axis: Acceleration Horizontal axis: Total mass of plates on the hanger Vertical axis: Total mass of plates on the hanger Horizontal axis: Mass of the cart + total mass of plates on the cart Vertical axis: Acceleration Horizontal axis: Mass of the cart + total mass of plates on the cart Vertical axis. Total mass of plates on the hanger Horizontal axis: Mass of the cart + total mass of plates on the cart + total mass of plates on the hanger Vertical axis: Acceleration Horizontal axis: Mass of the cart + total mass of plates on the cart + total mass of plates on the hanger
