A parachutist jumps from a height of 3.1 x103 m and free-falls for 10s. He then opens his parachute and for the next 20s slows down with an acceleration of -4.5 m/s2. After that he falls the rest of the distance to the ground at a uniform velocity.

a. What is his velocity just before the parachute opens?

b. At what altitude does the parachute open?

c. What is his velocity just before he lands?

d. How long does the entire jump last?

e. From what height would he need to jump from (without a parachute) in order to hit the ground at the same speed as in c)?
