A car is stopped with its front wheels resting against a curb when its driver starts the engine and tries to drive over the curb. Knowing that the radius of the wheels is 280 mm, that the coefficient of static friction between the tires and the pavement is 0.90, and that 60 percent of the weight of the car is distributed over its front wheels and 40 percent over its rear wheels, determine the largest curb height h that the car can negotiate:

1. A rock is thrown straight up from a bridge at 16m/s and misses the bridge on its way down falling into the water 15m below.
a) What is the maximum height above the water reached by the rock?
b)What is the rock's velocity at the instant before it strikes the water?
2. Car A is driving east at 120 km/h. Car B is driving we

You are trying to raise a bicycle wheel of mass and radius up over a curb of height . To do this, you apply a horizontal force .
1. What is the least magnitude of the force that will succeed in raising the wheel onto
the curb when the

We are conducting an experiment with two different masses. We have a car on a track tied to a weight that is off of a table rounded by a pulley. When we let go of the car, the weight falls to the ground and the car accelerates toward to the pulley.
Derive an equation for final velocity in terms of masses and initial height.

A car with a constant speed of 83.0 km/h enters a circular flat curve with a radius of curvature of 0.400 km. If the friction between the road and the car's tires can supply a centripetal acceleration of 1.25 m/s^2, does the carnegotiate the curve safely? Justify the answer.

A car with a constant speed of 83.0 km/h enters a circular flat curve with a radius of curvature of .400 km. If the friction between the road and the car's tires can supply a centripetal acceleration of 1.25m/s^2, does the carnegotiate the curve safely? Justify your answer.

A crate is resting on a ramp that is inclined at an angle above the horizontal. As it increased, the crate remains in place until it reaches a value of 29.2°. Then the crate begins to slide down the slope.
(a) Determine the coefficient of static friction between the crate and the ramp surface.
(b) The coefficient of kinet

A car goes up some hill at an angle theta.
The FBD shows that in the y-direction: n = mg*cos(theta), where n is the normal force.
In the x-direction:
T - mg*cos(theta) - mu*(mg*sin(theta)) = m*a_x (where T is the thrusting force of the car).
Is it possible to figure out what the thrusting force will be before-hand,

1. A roller coaster ride at an amusement park lifts a car of mass 700kg to point A at a height of 90 m above the lowest point on the track, as shown above. The car starts from rest at point A, rolls with negligible friction down the incline and follows the track around a loop o

Part 1:
Using web resources, and/or other materials, find the gas mileage of your dream car or any car of your choice. Let x be the number of miles driven on 50 gallons of gas. By setting up and solving a proportion involving x, find the value of x for the car that you have chosen. State the type of car, the mileage, and show b
