Bart and Nelson challenged each other to a bumper car game. Bart, whose car had a mass of 120 kg (with him in it), traveled west at a velocity of 9 m/s. Nelson and his car had a total mass of 150 kg traveled a velocity of 7 m/s east, heading towards Bart. The two had a head-on collision. Use the frame of reference in which the east is positive.

a) If Bart left the collision at a velocity of 7 m/s east, what velocity did Nelson leave with?

b) Determine the total kinetic energy for Bart and Nelson before the collision. Determine the total kinetic energy after the collision.

c) Instead of heading towards each other, Bart was going 9 m/s east following behind Nelson, whose velocity is still 7 m/s east. At what velocity would Bart travel at after the collision if Nelson left the collision with a velocity of 7 m/s east?

To compare two kinds of bumper guards, six of each kind were mounted on a car. Then the car was run into a concrete wall. Statistics for the costs of repairs are: ¯x1 = 140, ¯x2 = 149, (s1)^2 = 80, (s2) ^2 = 82. Assume that the two populations are normal, independent and have the same variance. Test at α = .01 the null hypothesis that there is no difference between costs of repairs.

At a county fair, two children ram each other head on while riding on the bumper car attraction. Jill and her car, traveling left at 3.50 m/s, have a total mass of 325 kg. Jack and his car, traveling to the right at 2.00 m/s, have a total mass of 290 kg. Assuming the collision to be elastic, determine their velocities after the collision.

In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at xr = 0 and the green car is at xg = 222 m. If the red car has a constant velocity of 25.0 km/h, the cars pass each other at x = 43.0 m. On the other hand, if the red car has a constant velocity...

A game is played as follows. There are 2 goats and 1 car, each hidden behind a numbered door. You choose a door (for simplicity you always choose door 1) and then Monty Hall opens one of doors 2 or 3.The door that he opens always reveals a goat. Now Monty offers you to switch yourchoice of doors (a) What is the probability that you win the car by switching your choice? Hint: Consider the events {Ci= car is behind...

Alice and Bob bet 50 dollars with each other in a game in which their friend Charlie tosses a two-sided coin 3 times in a remote location. If Alice correctly predicts the majority face (i.e. the face which occurred the most often in the three tosses), she gets to keep Bob's money as well. Charlie calls them and lets them know that at least 1 heads has occurred.a) Assuming that the coin was fair, what is the probability that the...

Consider two products whose demands are independent of each other. Assume that their demands are Normally distributed and they have identical cost structures. Assume we use the newsvendor model covered in the class, which gives you a framework for how one makes inventory decisions under demand uncertainty. If we combine the demands of the two products (i.e. Pool the demands) will the total inventory decrease or increase as compared to making decisions separately for the two products. Show your arguments...
