A car (m = 2000 kg) is traveling down a 15 degree incline at 65 m/s. The driver slams on the breaks causing the wheels to lock. Omega_x = 0.3. How far S will the tires skid on the road? If the driver can skid only 10 m before hitting another vehicle, how fast will the driver hit the other vehicle?

Part A. The sports car, having a mass of 1700 kg, is traveling
horizontally along a 20° banked track which is circular and has a
radius of curvature of ρ = 100 m. If the coefficient of
static friction between the tires and the road is
μs = 0.2 . Determine the maximum constant speed
at which the car can travel without sliding up the slope. Neglect
the size of the car.
Part B. Using Data in Part A, determine...

A car of mass M = 1500 kg traveling at 65.0 km/hour enters a banked turn covered with ice. The road is banked at an angle ∘, and there is no friction between the road and the car's tires as shown in (Figure 1). Use g = 9.80 m/s2 throughout this problem. What is the radius r of the turn if θ = 20.0 ∘ (assuming the car continues in uniform circular motion around the turn)?

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...

A 1500 kg car traveling at 19 m/s suddenly runs out of gas while
approaching the valley shown in the figure(Figure 1). The alert
driver immediately puts the car in neutral so that it will roll.
What will be the car’s speed as it coasts into the gas station on
the other side of the valley? Express your answer to two
significant figures and include the appropriate units.
Gas station 15 m 10 m
