Question

Problem 6.49 1 of 6 Constants I Periodic Table 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 44 angle. You estimate that the mass of the sled, with your friend on it, is 72 kg and that you're pulling with a force of 78 N Part A What answer will you give? -46.54 Previous Answers Request Answer Submit X Incorrect; Try Again: 7 attempts remaining Provide Feedback Next
