Work done by Non-Conservative Forces: Astudent drags a 7.0 kg carton of apples from rest across the floor by exerting a 45 N force in the direction shown in Figure below. The coefficient of friction (1) between the carton and the floor is 0.52. F=45N \\[\\p =0.52 Answer the following questions: You must draw the free body diagram and show full work. . Draw the free body diagram of the system indicating all the forces acting on the object. . What is work done on the carton by the applied force in moving it 10 meters? . What is the work done on the carton by gravity? . What is the work done on the carton by the normal force? . What is work done on the carton by the frictional force? . What is the net work done? . What is the speed of the carton after 10 meters? OMmMmUOwW> 0.5 points g A girl on asled coasts down a ski slope in Pocono Mountains. Her speed is 7.4 m/s when she reaches level ground at the bottom of the flat ski slope. The coefficient of kinetic friction () between the sled's runners and the hard, icy snow is 0.065, and the girl and sled together weigh 633 N. How far (in meters) does the sled travel on the level ground before coming to rest? (Hint: Use Kinetic Energy equation and work done by non-Conservative forces to get the distance traveled by the skier before coming to rest.)

It then runs into and compresses a spring, until the package momentarily stops. Its path to the initially relaxed spring is frictionless, but as it compresses the spring, a kinetic frictional force from the floor of an unknown magnitude acts on the package. If k = 10 000 N/m and the spring is compressed by a distance of 5 cm (0.05m) when the package stops, what is the magnitude of the retarding frictional force?
