Pаrt 1 (Tоtаl 20 pоints) A mаn pushes a 55.0 kg blоck of ice across a frozen lake at constant velocity. The applied force is shown as F at the 30 degree angle shown below. The magnitude of F is 60 N. A) Calculate the friction acting on the block. (5 points) B) Calculate the normal force acting on the block. (5 points) C) Calculate the coefficient of kinetic friction between ice and ice. (5 points) D) If the contestant increases his force to 70 N at 30 degree angle, and the kinetic friction remains the same, what is the acceleration of the block? (5 points) Part 2 (Total 5 points) A 9 kg object is falling down in air, experiencing air resistance. Density of air is 1.21 kg/m3, surface area of the object is 0.05 m2, drag coefficient of the object is 0.45 Calculate the terminal velocity of the object.
