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 spaceship has a mass of 600 kg at rest and accelerates to high speed. A person at rest on the ground observes that the spaceship has 1000 kg. How fast (in x 108 m/s) is the spaceship?
The carbon isotope 14C is used for carbon dating of archaeological artefacts. 14C decays to 14N by a process known as beta decay, in which the nucleus emits an electron (also known as a beta particle) and a subatomic particle called a neutrino. In one such decay, the electron and the neutrino are emitted in opposite directions to each other. The electron has a speed of 4 x 107 m/s and the neutrino has a momentum of 8 × 10-24 kg m/s. What is the recoil speed (in m/s) of the resulting 14N nucleus? (Take the mass of the carbon-14 and nitrogen-14 nuclei to be 2.34 x 10-26 kg and the mass of the electron to be 9.11 x 1031 kg. If you were aware of such things and concerned, please ignore relativistic effects.)
1. In an experiment, you throw a rubber ball of mass m = 25.0 g onto a block of mass M = 250 g that is initially at rest at the edge of a table of height h = 0.98 m. (Figure) The ball bounces back with a speed of 1.01 m/s, and the block eventually lands at d = 1.02 m from the bottom of the table. What is the speed of the ball, right before it hits the block?
Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.70 m/s, and bumper car 2 is traveling 79.1° south of west at 4.25 m/s. They collide and stick together, as the driver of one car reaches out and grabs hold of the other driver. The two bumper cars move off together after the collision, and friction is negligible between the cars and the ground.
