Best ResponseYou've already chosen the best response.2Arianna kicks a soccer ball off the ground and in the air with an initial velocity of 42 feet per second. Approximately what maximum height does the soccer ball reach? I think this can not be solve due to lack of data.

Best ResponseYou've already chosen the best response.2use the formula to get maximum height first \[S_2  S_1 = V_1 t + \frac12 at\] s2 is the maximum height = not given s1 is initial height = 0 V1 is the initial velocity = 42 a = 9.8 m/s^2 t = time =not given

Best ResponseYou've already chosen the best response.0you have to deal with two components of the balls motion ie vertical and horizontal

Best ResponseYou've already chosen the best response.2use another formula \[V_2 = V_1 + at\] v2 is final speed which will be 0 because v = 0 at max height v1 = 42 a = 9.8 now solve this... \[0 = 42 9.8t\] \[9.8t = 42\] can you solve for t?

Best ResponseYou've already chosen the best response.2btw...you need to multiply the time you get from that by 2 because the one we got was just the first half
