Question about Air resistance. Help !!?

Question

A skydriver jumps from a helicopter hovering at high altitude. If there were no air resistance, how fast would she be falling 12s after jumping?

Answer 1

V = a * t

a = -9.8 m/s^2 (the force of gravity on earth)

t = 12s (given)

Since we are ignoring air resistance (I feel very bad for your skydiver in this case, since a parachute is useless without air resistance), the equation is just plug and chug:

v = -9.8 * 12 = -117.6 m/s (negative sign means falling to the ground)

That's 263 miles per hour. It's a very good thing the world of physics problems is not the same as our own.
