A runner accelerates from 8 m/s to 20 m/s in 4 seconds. What is the runner's acceleration and how far do they travel in this time?
💡 Hint: Break it into two parts: first calculate acceleration, then use it to find distance.
A jet fighter reduces its speed from 300 m/s to 100 m/s in 5 seconds. Calculate the acceleration and the distance covered during this time.
💡 Hint: Remember to consider the negative sign in acceleration when calculating distance.
