A car is traveling in a straight line path at a maximum speed of 7.00 m/s. The driver of the vehicle applies the brakes bringing the car to a stop after traveling 10.0 m. What is the magnitude of the car's acceleration to the nearest hundredths place?

Explanation:

An object is traveling at constant acceleration if its changes in speed are constant at the same intervals of time.

The acceleration can be calculated as follows:

Where vo is the initial speed, vf the final speed and t is the time.

The acceleration and the distance x are related through the following equation:

The car has an initial speed of vo=7 m/s when the driver stops the car (vf=0) after traveling x=10 m.

The acceleration can be calculated by solving the last equation for a:
