Question
13. The distance s, in metres, fallen by a skydiver t seconds after jumping (and
160(:1 – 1 + e-5.
before the parachute opens) is s =
160(t – 1 + e¯4
a. Determine the velocity, v, at time t.
b. Show that acceleration is given by a =
10 - iv
c. Determine v, = lim v. This is the “terminal" velocity, the constant velocity
attained when the air resistance balances the force of gravity.
d. At what time is the velocity 95% of the terminal velocity? How far has the
skydiver fallen at that time?
