Two penguins, Wheezy and Mumble, are racing down an icy slope into the water below. Wheezy has a mass of 22 kg. Mumble has a mass of 25 kg. The slope is angled at eight degrees to the horizontal. They both start from the same position at the same time, and slide down the icy slope entirely due to gravity alone. There is a coefficient of kinetic friction of 0.12 between the penguins and the ice. Who wins the race and what is the winner's acceleration when they reach the finish line (ie the water)?

Chapter 06, Problem 066 GO In the figure here, block 1 of mass 2.4 kg and block 2 of mass 3.4 kg are connected by a string of negligible mass and are initially held in place. Block 2 is on a frictionless surface tilted at 0 = 28 °. The coefficient of kinetic friction between block 1 and the horizontal surface is 0.28. The pulley has negligible mass and friction. Once they are released, the blocks move. What then is the tension in the string? Number Unit the tolerance is +/-5% Click if you would like to Show Work for this question: Open Show Work
