A 49g marble moving at 1.9m/s strikes a 24g marble at rest. Assume the collision is perfectly elastic and the marbles collide head-on.
Part A What is the speed of the first marble immediately after the collision?
Part B What is the speed of the second marble immediately after the collision?
One mole of hydrogen gas at 22 C is compressed through an isobatic process to half its original volume
A 37-kg girl is bouncing on a trampoline. All through a certain interval after she leaves the surface of the trampoline, her kinetic energy decreases to 215 J from 430 J. How high does she rise during this interval? Avoid air resistance.
Three spheres, each with a negative charge of 4.0 X 10^-6 C, are fixed at the vertices of an equilateral triangle whose sides are 0.20 m long. Compute the magnitude and direction of the net force on each sphere.
A jetliner, traveling northward, is landing with a speed of 65m/s. Once the jet touches down, it has 715 m of runway in which to reduce its speed to 6m/s
A vertical container with base area measuring 16 cm by 18 cm is being filled with identical pieces of candy, each with a volume of 50 mm3 and a mass of 0.020g. Suppose that the volume of the empty spaces between candies is negligible.
A hot (70 C) lump of metal has a mass of 250 gm and a specific heat of .25 cal/gm-C. John drops the metal into a 500 gm calorimeter (specific heat of .10 cal/gm-C) containing 75 g of water at 20 C. Once they reach equilibrium, what will be the fin..
