A 6.8 kg penguin is sliding on a frictionless horizontal surface with an initial speed of 4.6 m/s. A varying magnitude force is applied in the direction of the motion. The force starts at 14.3 N and decreases at a constant rate so that the force is 9.6 N after 14 seconds.
What is the penguin's speed after 8.1 seconds?
Hint: Find force at 8.1 seconds.
