Arianna kicks a soccer ball off the ground and in the air with an initial velocity of 42 feet per second. Approximately, how long does it take until the soccer ball hits the ground again?

    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?

    btw...you need to multiply the time you get from that by 2 because the one we got was just the first half
