See Problem 2 on the first practice exam. In this problem, is the car experiencing static or kinetic friction while on the snow?
Is it experiencing static or kinetic friction on the ice?
If the hill has a slope of 15◦ , determine the coefficient of friction on the snow, and on the ice. (I wound up making up nice and simple numbers for you to do this problem; it turns out this car has some very nice snow tires!)
This is question 2 from the practice exam :
A Syracusian lives at the top of a snowy hill. They are having trouble getting their car up the hill, though, since there is an icy patch that is d = 20 meters long in the middle of the hill; when they try to drive up the ice, they slide back down. (If the driver can make it past the icy patch, they will be fine.) The driver has an idea: they will accelerate as much as possible on the snow, and hope that they can make it past the ice before they slide back down.1 When the car is on snow, it accelerates forward at 1 m/s 2 ; when the car is on ice, however, it accelerates backwards at 2 m/s 2 .
Please find both the coefficient of friction for snow and ice. It's supposed to kinetic on ice and static on snow. Please do find both, I have posted this question two or three times now. It's so bad, I have run out of questions and keep spending three dollars to post this. I keep trying because I really need this.
Thank you in advance.

draw free body diagram A boxed cake is placed in the trunk of a car to be delivered to a birthday party. The coefficient of static friction is 0.15 and for kinetic friction is 0.11. What is the minimum 0-60 mph time that the car can accelerate and keep the box from sliding? In other words, what is the shortest time for the driver to accelerate from a stop up to 60 mph and not have the box slide back...
Our favorite crate full of armored armadillos is sitting at the bottom of a hill that is inclined 41° above the horizontal. The crate is 75 kg and the coefficient of kinetic friction between the crate and the ground is 0.31. Samer decides to drag the crate to the top of the hill, which is 20 m above the base of the hill. Samer attaches a thin rope to the crate so that when he pulls, the rope will be...
General Physics with Calc 1 8. A package of dishes (mass 50.0 kg) sits on the flatbed of a pickup truck with an open tailgate. The coefficient of static friction between the package and the truck's flatbed is 0.310, and the coefficient of kinetic friction is 0.240. (a) The truck accelerates forward on level ground. What is the maximum acceleration the truck can have so that the package does not slide relative to the truck bed? (b) The truck barely...
5, Some of the funniest videos on the web involve motorists sliding uncontrollably on icy roads. Here let's compare the typical stopping distances for a car sliding to a stop from an initial speed of 10.0 m/s on a dry horizontal road, an icy hori- zontal road, and (everyone's favorite) an icy hill. (a) How far does the car take to slide to a stop on a hori- zontal roadi if the coefficient of kinetic friction is = 0.60, which...
Problem A car travels at a constant speed of 29.5 mi/h (13.2 m/s) on a level circular turn of radius 46.0 m, as shown in the bird's-eye view in Figure 7.13a. What minimum coefficient of static friction, Aus, between the tires and the roadway will allow the car to make the circular turn without sliding? Strategy In the car's free-body diagram (Fig. 7.13b) the normal direction is vertical and the tangential direction is into the page (step 2). Use Newton's...
Halliday, Fundamentals of Physics, 10e PRINTER VERSION BACK Chapter 06, Problem 018 You testify as an expert witness in a case involving an accident in which car A slid into the rear of car B, which was stopped at a red light along a road headed down a hill (see the figure). You find that the slope of the hill is 6 12.0, that the cars were separated by distance d - 22.0 m when the driver of car A...

Instructions: 1. Draw the schematic of the situation described in the wording of the problem. This schematic includes a list of the data given in the wording of the problem, such as initial position (x, yo), initial velocity Ivo, V, Vol, final position (x,y), final velocity (V, V, W) or maximum height (ym). Make a decision on whether you want to use "y" or "h" for the vertical axis and keep it consistent throughout all the problems. Write down the...
