Prectice Problens (PHYS 201o ersinn Problem 1: F 60. N A 30.0-kg sled is being pulled along a horizontal surface by a rope. The pulling force F is equal to 60.0 N and is directed 30.09 above the horizontal. The coefficient of kinetic friction between the box and the surface is equal to 0.1 30. Horkzontal surlace A. Draw FBD. What is the magnitude of the normal force that acts on the of the friction force that acts on the sled? sled? What is the magnitude Sin e 50 os B. What is net force on the sled? What is the direction and magnitude of the acceleration of the box? C. Assuming the sled started from rest, what distance will the box have traveled in 3.0 seconds? D. How much energy is transformed into thermal energy during those 3.0 s?
