9:46 4 will 4G The distance s (in m) Class above the ground for a projectile fired vertically upward with a velocity of Discussion 4 [a] m/s as a function of time t (in s ) is given bys = 4 [a] t - 4.9 t2 . Your instructor will provide you with a. Simply replace the letter with the corresponding digit. Do not multiply. For example, if [a] = 1, then 4 [a] is 41. 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? State the value you are using for a before you show the work to answer these four questions. Remember to use the Canvas Equation Editor. Refer to the Tools for Mathematics page in the Course Specific Information module for technical guidance. Post your answers in the discussion area by the end of the fourth day of the module week. erau.instructure.com
