A ball of masses m1=0.22kg that is moving with a speed of 5.5m/s( positive x direction) collided head on and elastically with another ball of unknown mass m2 initially at rest. Afterward the incoming ball m1 bounces backwards with a speed of 3.5m/s. A) calculate the velocity of the target ball m2 after the collision B) calculate the mass m2 of the target ball C if the collision lasts 0.1seconds what is the magnitude of the average force during the collision?

Calculate the probability that an electron in the ground state of a hydrogen atom will be found at a greater distance from the nucleus than would be allowed classically.
A pendulum is made by letting a 3 kg object swing at the end of a string that has a length of 2.0m. The max angle the string makes by vertical as the pendulum swings is 30degrees. What is the speed of the object when it’s at 15degrees?
A well-insulated piston- cylinder device contains 6kg of superheated R-134a initially at 0.10Mpa and -10 degrees Celsius is compressed to a final state at 0.50mpa and 80 degrees Celsius. find the work required for this compression process
A sealed tank containing seawater to a height of 11.1 also contains air above the water at a gauge pressure of 2.95. Water flows out from the bottom through a small hole.
A string 120 cm long with a linear mass density 10^-2 kg/m is stretched to a tension of 36 N. The string is attached between two walls and when plucked forms a standing wave with 3 antinodes. Find the frequency of vibration. A standing wave pattern c..
