Question: A stationary particle having a rest mass energy of 1400MeV disintegrates into two particles called "pions," a π+ and a π-, that travel in opposite directions, as shown schematically in Fig. Each of the pions has a rest-mass energy of 140MeV.
Fig. - A particle disintegrate into two points
a. Find the kinetic energy, in appropriate units, of each outgoing particle.
b. What is the value of γ ("gamma") for either pion?
c. When the pions are at rest, they have a lifetime of 0.28ns. According to an observer in the laboratory, what is the lifetime of the moving pions (in ns)?
A 20-kg object on a frictionless horizontal surface oscillating on a spring that has a force constant equal to 3.5 kN/m has a total mechanical energy of 0.60 J. (a) What is the amplitude of the motion?
Nature of light and how we know light acts in that way?
A 56kg skier starts from rest at the top of a 1200-m long trail which drops a total of 230.00 m from top to bottom. At the bottom, skier is moving 11m/s. How much energy was dissipated by friction?

A child bounces a 56 g superball on the side walk. The velocity change of the superball is from 24 m/s downward to 18 m/s upward. what is the magnitude of the force exerted on the superball
For a standard production car, the highest road-tested acceleration ever reported occurred in 1993, Calculate the magnitude of the car's acceleration
In the lab you place a beaker that is half full of water (density ρw) on a scale. You now use a light string to suspend a piece of metal of volume V in the water. The metal is completely submerged, and none of the water spills out of the beake..
The water is near freezing in temperature. Typically a human can only swim in such water for about 5 minutes before hypothermia sets in. Calculate the time the explorer spends in the water if the river is 91.9 feet wide
