What's the kinetic energy of the roller coaster at the top and bottom of the hill? Use KE =7mu2 A kiddie roller coaster car has a mass 100 kilograms. At the top
doubles. The car's kinetic energy at the bottom is
of a hill, it's moving at a speed of 3 meters/second. After reaching the bottom of the hill, its speed
v its kinetic energy at the top. The car has
joules of kinetic energy at the bottom of the hill.

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c
