You have been hired as an expert witness in a court case involving an automobile accident. A piece of a bullet was found in the accident. The force on the bullet is given by the formula F=580 – (1.80 x 10^5)t over the time interval t=0 to t = 3.0 x 10^-3s. In this formula, t is in seconds and F is in newtons.
(i) Sketch a graph of F vs. t for t=0 to t = 3.0 ms.
(ii) Using graphical methods, estimate the impulse given by the bullet.
(iii) As a result of this impulse, the bullet achieves a speed of 220 ms-1, given to it in the barrel of a gun, what must its mass be?
(iv) The accident involved car A of mass 1900 kg which crashed into stationary car B of mass 1100 kg. The driver of car A applied his brakes 15 m before he crashed into car B. After the collision, car A slid 18 m while car B slid 30 m. The coefficient of kinetic friction between the locked wheels and the road was measured to be 0.60. Determine the velocity for each car after the collisions.

There is a constant force from the wind, F_wind, blowing to the right, so the mass is initially at rest, but hanging at an angle Theta from the vertical because of the presence of the wind. Suddenly, spring breaks, and the mass drops under the influence of F_wind (note F_air and F_wind are the same constant vector!) and its weight.
