The speed of of ocean waves v (measured in m/s) depends on their wavelength . ( in m) and the accelaration due gravity g(measured in m/s') in this way; v- g. if the eqaution is correct dimensionally what is the value of the exponent c? a. 1 b. 2 c. 2/3 d. 1/2

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
