Transcribed Image Text:

V = 1.0 m/s 20 P=0.10 Santa Claus loses his footing and slides down a snowy roof at an angle of 20, with an initial velocity (vo) of 1.0 m/s. Santa has a mass of 82 kg. Between the surfaces of the roof and Santa, the coefficient of kinetic friction () is 0.10. 1. Draw and label a force diagram for the system that includes only Santa. Include dashed lines to represent components of forces perpendicular to and parallel to the roof, and draw equivalence marks on any forces (or components of forces) that are equal in magnitude. 2. Calculate the weight (F) of the Santa, assuming he is near the surface of the Earth, where g = 9.8 m/s. 3. Write a Newton's 2nd Law equation for the forces on Santa that are perpendicular to the surface of the roof. Solve for the normal force (F) the roof exerts on Santa.
