You are designing a circular unbanked freeway ramp with a radius of 100. m, the coefficient of static friction between the tires and asphalt is 0.800 dry and 0.400 wet. Find the maximum speed that a car can travel through the ramp during when the road is dry and wet in mph (miles per hour). Vmax, dry = Vmax, wet =

A civil engineer wishes to redesign the curved roadway in the figure in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked, which means that the roadway is tilted toward the inside of the curve. Suppose the designated speed for the road...

Curved portions of highways are always banked (tilted) to prevent cars from sliding off the highway. A car of mass m moves at a constant speed v around a banked circular track of radius R as shown in the figure. If the frictional force from the track is negligible, what bank angle Ѳ prevents sliding.

Use the picture below to
determine the radius of the off ramp from the 405 to the 105. If
the recommended speed of the turn is 45 mi/hr (convert to m/s),
what is the angle the turn is banked so that friction is not needed
to keep the car from sliding towards the outside of the ramp? The
off ramp is partially highlighted in green. Use the portion between
the red lines and the scale in the lower left to...

As depicted in the figure, a barrel rolls down a ramp and flies off the end with velocity o 15 (m/s) at an angle 0 20 with respect to the horizontal. The barrel lands a distance L along the slope (measured from the end of the ramp where the barrel becomes airborne). Note that the slope is inclined at p 30 relative to level ground a) How far down the slope, L, does the barrel land, and how long, T,...
