Q1. A Nordic jumper goes off a ski jump at an angle of 10.0° below the horizontal, travelling 105 m horizontally and 55 m vertically before landing. (a) Ignoring friction and aerodynamic effects, compute the speed needed by the skier on leaving the ramp. (b) Olympic Nordic jumpers can make such jumps with a jump speed of 23 m/s that is considerably less than the answer found in part. Describe how that is possible.

Q2. A plane slows down from 142 m/s to 1 m/s in 3200 m.

A. What is the acceleration of plane?

B. How long does it take the plane to travel this distance?

C. Plot the position, velocity, and acceleration of the plane throughout this time interval as a function of time, using initial position of the plane as the origin.
