Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

You are a bully. You pin a 48 kg dweeb to a wall so that his feet aren't touching the ground. Your arm is extended so that it makes an angle 28 degrees with the horizontal. The dweeb's back is so sweaty with fear that there is no friction between his back and the wall. What is the magnitude of the force , in N, you must apply to keep the dweeb in equilibrium? (Use g = 10 m/s2) This scenario is represented schematically below. Unfortunately for you, years later the dweeb is your boss and he makes your life miserable. (Please answer to the fourth decimal place - i.e 12.3445)
An early submersible craft for deep-sea exploration was raised and lowered by a cable from a ship. When the craft was stationary, the tension in the cable was 6500 N. When the craft was lowered or raised at a steady rate, the motion through the water added an 1800 N drag force. What was the tension in the cable when the craft was being lowered to the seafloor?
A heavy crate is suspended from two ropes as it is lowered from a high shelf to the floor at a constant speed.

A 17-year-old employee working for Southern Virginia College's (SVC) bookstore during the summer months is helping prepare for Fall sales. It's a good way to make extra money, and the teen is saving for a car. Books from one supplier are shipped to the SVC bookstore in large crates equipped with rope handles on all sides. On one occasion, the teen momentarily pulled with a force of 707 N at an angle of 33.7° above the horizontal to accelerate a 121-kg crate of books. The coefficient of friction between the crates and the vinyl floor is 0.55. Determine the acceleration experienced by the crate in m/s2. Use the approximation g ≈ 10 m/s2.

On her way to visit Grandmother, Red Riding Hood sat down to rest and placed her 1.20 kg basket of goodies beside her. A wolf came along, spotted the basket, and began to pull on the handle with a force of 6.40 N at an angle of 25 degree with respect to vertical. Red was not going to let go easily, so she pulled on the handle with a force of 12.2 N. If the net force on the basket is straight up, at what angle was Red Riding Hood pulling from the vertical?
