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.
A freight train consists of two 8.00×105-kg engines and 45 cars with average masses of 5.50×105kg. (a) What force must each engine exert backward on the track to accelerate the train at a rate of 5.00×10−2m/s2 if the force of friction is 7.50×105 N, assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains is small, and consequently trains are very energy-efficient transportation systems. (b) What is the magnitude of the force in the coupling between the 37th and 38th cars (this is the force each exerts on the other), assuming all cars have the same mass and that friction is evenly distributed among all of the cars and engines?
A car that weighs 1.30 * 104 N is initially moving at 40 km/h when the brakes are applied and the car is brought to a stop in 15 m. Assuming the force that stops the car is constant, find (a) the magnitude of that force and (b) the time required for the change in speed. If the initial speed is doubled, and the car experiences the same force during the braking, by what factors are (c) the stopping distance and (d) the stopping time multiplied? (There could be a lesson here about the danger of driving at high speeds.)
A freight train consists of two 8.00×104 kg5.60×104 kg engines and 45 cars with average masses of 5.50×104 kg5.50×104 kg.

This is not a large frictional force for such a massive system. Rolling friction for trains is small, and consequently, trains are very energy-efficient transportation systems.
