In Practicals you send a cart of mass 0.55 kg along a track with an initial velocity of +72 cm/s. It rolls for a while, then it collides with a fixed forcesensor at the end of the track, and reverses its direction. Shown is the Motion Sensor data giving the velocity versus time. The sensor was set to record 60 samples per second. Which of the following is the best estimate for the change in momentum of the cart during the brief collision at t ≈ 1.3 s?
