A 60kg (including equipment) Olympicski-jumper starts with pushes off from the starting gate (A),giving her an initial velocity of 3m/s. She skis down thefrictionless slope shown below and launches from the jump(B).
(a) What is the maximum speeds he attains?
(b) With what velocitydoes she leave the jump?
(c) After 2 seconds in theair, where is the skier, relative to the edge of thejump?
(d) At the peak of herjump, an errant biathlete shoots her with a 25g bullet, travellingat 350 m/s. By how much does her speed at this point change ,assuming the bullet lodges in her ski-boot?
