friction 1. i am hauling 230㎏ of firewood on a sled, puig with 710n of force on a rope over my shoulder at a 72 degree angle from the sled. the sled starts to accelerate at 0.12mis. what is the coefficient of friction between the ground and the sled? 2. there is a 4kg book sitting on a table. igive the book a push·ltstarts off sling at 25msec then slides to a stop in 1.7m. what is the coefficient of friction between the book and the table? 3. the 1992 1500kg mazda rx-7 could go from 60mph-0 in 119ft. what is the coefficient of friction between the tires and the tarmac? 4. i am walking down a 20 degree slope and i step on a banana peel with a kinetic coefficient of friction of 0.013. assuming i have a mass of 120kg, how fast do i start sliding down that hil?
