The 80-kg box is connected to a car with an angle of 65 degrees with the ground. The box at rest is then pulled by the car for 10m. When the box is traveling at 4 m/s, the cable breaks. The box slides for 1.5 seconds and it comes to a full stop. What is the average tension in the the cable? What is the coefficient of friction?

A 5.35-kg box is pulled up a ramp that is inclined at an angle of 33.0° with respect to the horizontal, as shown below. The coefficient of kinetic friction between the box and the ramp is 0.165, and the rope pulling the box is parallel to the ramp. If the box accelerates up the ramp at a rate of 2.09 m/s2, what must the tension FT in the rope be? Use g = 9.81 m/s2 for the acceleration due to...
