A drag racer must accelerate from rest to a speed of 80 m/s. If the car accelerates uniformly at 4.0 m/s², what is the minimum track length required to reach this speed?
- 750 m
- 800 m
- 850 m
- 900 m

A tennis ball machine is being tested by launching a ball straight upward from a height of 1.2 meters. The ball rises to its maximum height and then falls back down, being caught by the machine at the same height of 1.2 meters from where it was launched.
The ball had an initial velocity of 25 ms
- Determine the total distance the ball travelled. (2 marks)
--- 5 WORK AREA LINES (style=lined) ---
- Determine the total flight time of the ball. (2 marks)
