Suppose that a highway offramp that I often use bends with a radius of 20 meters. I notice that my car tires allow me (in good weather) to take this offramp at 15 m/s without slipping. How large does the offramp's bending radius need to be for me to be able to make the turn at 30 m/s instead (without slipping)?

A flat (unbanked) curve on a highway has a radius of 250 m
A flat (unbanked) curve on a highway has a radius of 250 m. A car successfully rounds the curve at a speed of 35 m/s but is on the verge of skidding out. a. Draw free body diagram of the car. b. If the coefficient of static friction between the car's tires and the road surface were reduced by a factor of 2, with what maximum speed could the car round the curve without slipping? c. Suppose the coefficient of friction were increased...

A banked circular highway curve is designed for traffic moving at 62 km/h. The radius of the curve is 214 m. Traffic is moving along the highway at 41 km/h on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to take the turn without sliding off the road? (Assume the cars do not have negative lift.)

A flat (unbanked) curve on a highway has a radius of 240 m . A car successfully rounds the curve at a speed of 37 m/s but is on the verge of skidding out. Part A If the coefficient of static friction between the car’s tires and the road surface were reduced by a factor of 2, with what maximum speed could the car round the curve? Express your answer in meters per second to two significant figures. part B...

1.On a hill Pick up trucks will often carry sand bags in the back to help with traction. Consider a truck of mass M=1500kg on a hill inclined at 5 degrees. Construct a free body diagram and use it to determine the minimum coefficient of friction so the truck does not slide down the hill. Using this coefficient of friction determine if the truck had 100 kg extra weight if it would slide down the hill or not (i.e. does...

Highway curves are "banked" inward, so gravity assists the car's traction. Suppose another highway curve has a radius of curvature of 500m. It is banked so that traffic moving at 30m/s can travel around the curve without needing any help from friction. a) Draw a force diagram for a car traveling around this curve at a constant speed. Draw the diagram so that you are looking at the rear of the car. Do not tilt your coordinate axes for this...
