Asky diver, with parachute unopened, falls 625 m in 15.0 s. then she opens her parachute and falls another 362 m in 139 s. what is her average velocity (both magnitude and direction) for the entire fall?
magnitude m/s
so for the free fall v = (a)(t) and because a = g in this instance i did v = (9.8)(15.0) = 147 m/s
so for the free fall velocity = 147
the second part is confusing, the parachute is open so a ! = 9.8 because of the wind drag on the chute, does a = 1/2gt^2? cause if it does i think i can figure it out.

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.
