14.2 Acceleration
Acceleration is the rate of change in the speed of an object. To determine the rate of acceleration, you use the formula below. The units for acceleration are meters per second per second or m/s2.

A positive value for acceleration shows speeding up, and negative value for acceleration shows slowing down. Slowing down is also called deceleration. The acceleration formula can be rearranged to solve for other variables such as final speed (v2) and time (t).

1.A skater increases her velocity from 2.0 m/s to 10.0 m/s in 3.0 seconds. What is the skater’s acceleration? Looking for
Acceleration of the skaterSolution

The acceleration of the skater is 2.7 meters per second per second. Given
Beginning speed = 2.0 m/s
Final speed = 10.0 m/s
Change in time = 3 seconds

2.A car accelerates at a rate of 3.0 m/s2. If its original speed is 8.0 m/s, how many seconds will it take the car to reach a final speed of 25.0 m/s? Looking for
The time to reach the final speed.Solution
The time for the car to reach its final speed is 5.7 seconds.

Beginning speed = 8.0 m/s; Final speed = 25.0 m/s
Acceleration = 3.0 m/s2

1.While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the automobile’s acceleration? (Remember that a negative value indicates a slowing down or deceleration.)

2.A parachute on a racing dragster opens and changes the speed of the car from 85 m/s to 45 m/s in a period of 4.5 seconds. What is the acceleration of the dragster?

3.The table below includes data for a ball rolling down a hill. Fill in the missing data values in the table and determine the acceleration of the rolling ball. Time (seconds)Speed (km/h)
