Arianna 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.

use 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

you have to deal with two components of the balls motion ie vertical and horizontal

use 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?
