m Use the pictures below to draw force diagrams for the cart in the experiment described above: the rst while it is increasing speed during the initial push, the second after the push, while the speed of the cart is gradually decreasing. Explain briey why you drew your diagrams as you did. Speeding up during inin'm' push Siowing down oer initial push If you have examined friction-type contact push/pull interactions in Unit EM of this course, you would have given a wooden block a push across the table and saw it slow and stop. We said this was due to 'friction', but how do you think friction actually works? 1'0 Whether you think friction is a force or not, explain what you think was actually happening that slowed the block down
