Adriver of a car traveling at 14.6 m/s applies the brakes, causing a uniform deceleration of 1.2 m/s2. how long does it take the car to accelerate to a final speed of 10.8 m/s? how far has the car moved during the braking period?

Recall that

It takes the car about 3.2 s to reduce its speed from 14.6 to 10.8 m/s, since

Next, recall that

Then the car undergoes a displacement of about 41 m, since

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
