a car is traveling at a constant speed of Vo on a straight, level road. After the brakes are applied at t=0 seconds, the motion can be approximated by: x=t^3/100-t^2 +17t where x is the distance traveled in meters and t is the time in seconds. Determine: A the initial velocity (Vo), B. the time required for the car to stop, C. The distance required for the car to stop, and D. The maximum deceleration during braking.

P2.4-4) A car initially traveling at 60 mph coasts for 5 seconds. Due to friction and wind resistance, the car decelerates while coasting at a rate of 1 ft/s2. After the 5 seconds of coasting, the driver applies the brakes and decelerates at a constant rate eventually bringing the car to a stop. If the total time that the car travels is 8 seconds, determine the car's braking acceleration. Given: Find: Solution: Draw the acceleration and velocity curves. v (ft/s)...

A test model for a new type of braking system is designed to apply a braking force that decays following an exponential function. For an object moving in the (+) x direction (to the right), the force acts in the opposite direction. When the brakes are applied, the velocity change as a function of time in seconds can be approximated by . v=v(t) = V, e-At where Vo is a constant in [m/sec) and A is a constant in [1/sec)....

In traveling a distance of 3.7 km between points A and D, a car is driven at 107 km/h from A to B for t seconds and 53 km/h from C to D also for t seconds. If the brakes are applied for 5.7 seconds between B and C to give the car a uniform deceleration, calculate t and the distance s between A and B.
