Acceleration – Practice
1) What is the acceleration of a train that has an initial speed of 2 m/s and it increases its speed to 24 m/s over a time interval of 110 seconds?
2) How long does it take a pigeon to accelerate from rest to 20 m/s if it accelerates at 4.5 m/s?
3) If a drag car accelerates at 3 m/s for 5 seconds to reach a final speed of 17 m/s, what was its initial speed?
1) 0.2 m/s2
2) 4.4 s
3) 2 m/s
