↑ It's a snowy day and you're pulling a friend along a level road on a sled. You've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. You've been walking at a steady 1.5 m/s, and the rope pulls up on the sled at a 36° angle. You estimate that the mass of the sled, with your friend on it, is 63 kg and that you're pulling with a force of 74 N. ↑ с ▼ Part A What answer will you give? 15] ΑΣΦ 0.144 Submit Provide Feedback www ?

Momo with mass m is sliding down an inclined plane that makes an angle O relative to the horizontal. The coefficient of kinetic friction between Momo and the inclined plane is uk. Obtain an expression for Momo's acceleration along the incline. Assign a rotated Cartesian plane so that the acceleration is along the positive x-axis and the normal force is along the positive y-axis. The component of the weight parallel to Momo's acceleration is wy = mg The magnitude of the frictional force is f = Hk The normal force on Momo is n = mg 0. With these expressions and applying Newton's second law, we arrive at an expression for Momo's acceleration: a =
