Question: A 6.1 kg penguin is sliding on a frictionless horizontal surface with an initial speed of 7.1 m/s. A varying magnitude force is applied in the direction of the motion. The force starts at 23.4 N and decreases at a constant rate so that the force is 9.0 N after 12 seconds. What is the penguin's speed after 8.3 seconds?
