A cart of mass 0.85 kg is on a track, connected by a string over a pulley to a hanging mass of 0.1 kg. A friction pad is attached to the bottom of the cart, and you push the cart so that it first moves toward the sensor, then away from the motion sensor. Assuming the magnitude of the force of friction remains constant throughout the entire motion of the cart, the magnitude of the net acceleration of the cart is which of the following? a. larger when the cart is moving towards the motion sensor b. larger when the cart is moving away from the motion sensor c. the magnitude of the acceleration cannot be predicted
