A 1,500-N crate is being pushed across a level floor at a constant speed by a force F of 370 N at an angle of 20.0° below the horizontal, as shown in the figure a below. F 20.0° / b 20.0° (a) What is the coefficient of kinetic friction between the crate and the floor? (Enter your answer to at least three decimal places.) 0.220 X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.
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)
You have devised an experiment to measure the kinetic coefficient of friction between a ramp and a mass. You place the mass on the ramp at an angle high enough that the mass starts sliding. You measure the time it takes to fall down a known distance. The time it takes to fall down the 45 degree ramp starting from a standstill is At = 0.46 sec, m=1 kg, and the distance it falls, Ax , is 0.5 m. What is µk? m Дх in At Uk

For Problems 1 and 2, use the following formula to describe the magnitude of a drag force: 1 D = — -CA pv² 2 FD Problem 1: When a car is traveling at a speed of 30 km/h, it experiences a drag force of magnitude F. If the car increases its speed to 40 km/h, what then will be the drag force it experiences? Assume the drag force is proportional to the square of speed.
10. a. In investigating an acccident, police find skid marks left by a car as the driver slammed on the brakes and the car skidded to a halt. The skid marks form a straight line 3.9375 m long on a flat road. It was raining and the coefficient of friction was 0.32125. The mass of the car is 1486.75 kg. What is the angle between the friction force and the displacment of the car? Previous submissions: b. Using W = F Ax cos 0, what was the work done by friction? Previous submissions: c. What was the AKE? Previous submissions: d. What was the initial velocity of the car? Take this to be positive.
