A billiard ball with v0 M = 10 m / s collides elasticly with another of the same mass, which is initially at rest. After the collision, the ball that was stopped fires forming an angle of 30 ° with the direction of the initial speed of the other ball. Calculate the modules of the final speeds of the two balls.
A 980-kg sports car collides into the rear end of a 2500-kgkg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 2.9 mm before stopping. The police officer, estimating the coefficient of kinetic friction between tires and road to be 0.80, calculates the speed of the sports car at impact. Question: What was the speed sports car at impact? v=??
As it is sliding across ice, an internal explosion breaks an 80 kg object into two pieces. One piece has a mass of 33 kg and moves off with a speed of 15 m/s at an angle of 40° relative to the initial path of the object. If the object was initially moving at 20 m/s. (a) What is the speed and direction of the other piece after the explosion? Be sure to explain how you are able to determine this. (b) Compare the kinetic energy of the single object before the explosion to the total ki- netic energy of the two pieces after the explosion. Explain how this relates to the term 'explosion'.

A shell is shot with an initial velocity v o of 21 m/s, at an angle of 00 = 57° with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass (see the figure). One fragment, whose speed immediately after the explosion is zero, falls vertically. How far from the gun does the other fragment land, assuming that the terrain is level and that air drag is negligible? Explosion Number Units

Moderating a Neutron In a nuclear reactor, neutrons released by nuclear fission must be slowed down before they can trigger additional reactions in other nuclei. To see what sort of material is most effective in slowing (or moderating) a neutron, calculate the ratio of a neutron's final kinetic energy to its initial kinetic energy, Kf/Ki, for a head-on elastic collision with each of the following stationary target particles. (Note: The mass of a neutron is m=1.009u, where the atomic mass unit, u, is defined as follows: 1u=1.66×10−27kg.) An electron (M=5.49×10−4u) Express your answer using four significant figures.Kf/Ki=
