A car is initially traveling toward SOUTH at a speed of 11.75 m/s. The brakes are applied and the car comes to a stop over a distance of 38.3 m (since the beginning of the application of the brakes). Take SOUTH as the positive direction.
(a) Find the car's acceleration in m/s2. Pay attention to its sign. Keep 2 decimal places.
Homework Answers
using 3rd equation of motion
v^2 = u^2 + 2 a d
0 = 11.75^2 + 2* a * ( 38 3)
a = - 1.8 m/s^2

A car is traveling with a constant speed when the driver suddenly applies the brakes, giving the car a deceleration of 3.50m/s2. The car comes to a stop in a distance of 34.0 m. What was an initial speed of the car? How long (the time) did it take for this car to stop? What was the car's speed when it had traveled 17.0 m from the point where the brakes were applied? How long did it take for this...

The brakes are applied to a car traveling on a dry, level highway. A typical value for the magnitude of the car's acceleration is 4.85 m/s2. If the car's initial speed is 28.5 m/s, how long does it take to stop and how far does it travel, starting from the moment the brakes are applied? time to stop? stopping distance?
