Overview
The distance s (in m) above the ground for a projectile fired vertically upward with a velocity of 40 m/s as a function of time t (in s) is given by s = 40t ? 4.9t².
Find the answers to these questions.
- find t for v = 0
- find v for t = 4
- find v for t = 5
- What conclusions can you draw?
