Answer the following questions

1. In general, the frictional force will increase as a surface becomes smoother. True or False 2. A toboggan with a mass of 12 kg is placed at the top of a snowy hill. What is the coefficient of static friction if the force of pushing the toboggan down the hill is 104 N? a) 1.13 b) 0.88 C) 0.31 d) 0.12 e) You cannot determine the static friction with the information given. 3. Using the diagram below, calculate the coefficient of kinetic friction for the toboggan on snow if a 32 kg boy was sitting on his toboggan with a mass 6.5 kg on a hill with an incline angle of 28 if the toboggan is accelerating down the hill at 2.4 m/s2. [Enter your value to 2 decimals] 4. It is important to pull the string parallel to the table to accurately measure the friction force because... (CHOOSE ALL THAT APPLIES) 5. pulling on an angle will change the friction force it would not be possible to measure the friction force additional tools would be needed to measure the friction force pulling on an angle will change the coefficient of friction the lab said to do it this way even though it does not really matter
