A crazed (and out of control) snowmobiler is sliding down a mountain side. The components of position for the snowmobile are as follows: x(t) = 0.25 t y(t) = 0.75 t z(t) = -0.15 t³ a) Find the expression for the velocity vector of the snowmobile. b) What is the magnitude of velocity at t = 3s? c) What are the directional cosines for velocity at t = 3s?
