the instructor gave me a=4. for example if a =4 then 4[a]=44.... s=44t-4.9t^2; find t for v=0; Find v for t=4; find v for t=5; what conclusions can be drawn from this? please show work step by step.

The distance s (in my above the ground for a projectile fired vertically upward with a velocity of 4 a] m s as a function of time tin's ) is given bys = 4 at 4.9t Your instructor will provide you with a. Simply replace the letter with the corresponding digit. Do not multiply. For example. if la - 1. then 4 Ja is 41. Find the answers to these questions. . find t for v = 0 . find v fort = 4 . find u fort - 5 .What conclusions can you draw
