29 Multiple choice questions covering speed, acceleration and velocity.
A paper airplane flies 2.8m in 1.8s. What is the airplane’s average speed?
Sav =d/t; Given distance of 2.8m and time of 1.6s;
2.8m / 1.6s=1.8m/s
A race car’s velocity increases from 4.0m/s to 36m/s over 4.0s time interval. What is the average acceleration?
Velocity final – Velocity initial / time taken
36m/s – 4m/s =32m/s
32 / 4= 8m/s^2
A quantity that has both magnitude and direction?
