Transcribed Image Text:

V = 1.0 m/s 20 H =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. Write a Newton's 2nd Law equation for the forces on Santa that are parallel to the surface of the roof. Calculate the net force on Santa and his acceleration. Is Santa speeding up or slowing down? a. If Santa is speeding up, calculate the displacement (s) and time interval (4t) required for him to reach a final velocity of 5.0 m/s. b. If Santa is slowing down, calculate the displacement (s) and time interval (At required for him to come to a complete stop.
