A car moving with a constant speed of 85 km/h enters a circular, flat curve with a radius of curvature of 0.40 km. If the friction between the road and the car’s tires can support a centripetal acceleration of 1.25 m/s2, without slipping, does the car navigate the curve safely, or does it fly off the road?
The car is travelling at a speed of 100 km/h and as it decelerates at 2 m/s^2. If the rain is falling at 6 m/s in the direction shown, determine the velocity and acceleration of the rain as seen by the driver.

11.78 A car is traveling at a constant speed of 54 km/h when its driver sees a child run into the road. The driver applies her brakes until the child returns to the sidewalk and then accelerates to resume her original speed of 54 km/h; the acceleration record of the car is shown in the figure. Assuming x = 0) when t = 0, determine (a) the time t, at which the velocity is again 54 km/h, (b) the position...
The automobile has a speed of 50 ft/s at point A and an acceleration having a magnitude of a = 20 ft/s2 , acting in the direction shown. Part A) Determine the radius of curvature of the path at point A. Part B) Determine the tangential component of acceleration. θ=30°
A car is moving on a city street at a speed of 30 km/h. The driver sees a red traffic signal ahead and slams on the brakes, providing an acceleration that has magnitude 6.0 m/s2. The driver's reaction time is 0.50 s. (a) Determine the displacement of the car until it stops. ___m (b) Repeat Part (a) if the initial speed is 60 km/h and the braking acceleration is the same as in Part (a). ___m
A 1100-kg car moving on a horizontal surface has speed v = 50 km/h when it strikes a horizontal coiled spring and is brought to rest in a distance of 2.3 m . What is the spring stiffness constant of the spring?
2. [6] As the car passes point A, it increases its speed at a constant rate of v1m/s, which is maintained as it passes point B. If the net acceleration at point B has a maximum value of 7 m/s, and the speed of the car is 25 m/s, determine the minimum radius of curvature ρ" of the road at B. 0.6m G
