Acceleration Calculations



Acceleration Calculations Name ________________

Acceleration means a change in speed or direction. It can also be defined as a change in velocity per unit or time.

a = vf – vi where a = acceleration

time vf = final velocity

vi = initial velocity

t = time

Calculate the acceleration for the following data.

Initial Velocity

1. 0 km/hr

2. 0 m/s

3. 20 km/hr

4. 50 m/s

5. 25 km/hr

6. 100 m/s

7. 12 m/s

Final Velocity

24 km/hr

35 m/s

60 km/hr

150 m/s

1200 km/hr

50 m/s

6 m/s

Time

3 s

5 s

10 s

8. A car accelerates from a standstill to 60km/hr in 10.0 seconds. What is its acceleration?

9. A car accelerates from 25km/hr to 55km/hr in 30 seconds. What is its acceleration?

10. A train is accelerating at a rate of 2.0km/hr/s. If its initial velocity is 20km/hr, what is its velocity after 30 seconds?

11. A runner achieves a velocity of 11.1 m/s 9 seconds after he begins.

a) What is his acceleration?

b) What distance did he cover?
