A pion lives 26 ns in its rest frame. It travels 15 cm down a beam pipe in a particle
accelerator before it decays into other particles. How far is this in the rest frame of the pion?

A pion lives 26 ns in its rest frame. It travels 15 cm down a beam pipe in a particle accelerator before it decays into other particles. How far is this in the rest frame of the pion?
A pion lives 18.2 ns in its rest frame. What does an observer in a laboratory in which the particle moves at a speed of 233106689.5 m/s measures the time (in ns) the particle lives for?
A subatomic particle has a 410 ns lifetime in its own rest frame. If it moves through the lab at 0.980 c, how far does it travel before decaying, as measured in the lab?
A pion is an unstable particle that has a mean lifetime of 2.55 x 10^-8 s. Thi si the time interval between its creation in a nuclear process and its extinction into decay products, as measured in a frame of reference at rest with respect to the pion. An average pion is traveling at 0.230 c relative to Earth. How far does it travel in its lifetime, relative to Earth?
5. A particle with a ‘proper’ lifetime (i. e. in its own rest frame) of 885. s is traveling towards earth with a speed of v=0.5 c. a. In its own rest frame, how far this particle travel, in m, during one lifetime (885 s)? b. In the earth’s rest frame, how far does the particle travel in 885 s?
An unstable particle of mass m decays in time t = 10^-10 s in its own rest frame. If its energy is E = 1000 mc^2 in the lab, how far (in meters) will it move before decaying? (Answer: 30 m)
Second part of part c) please! The bit that asks about the
particle travelling 75m in the laboratory before it decays.
Determine its lifetime in the lab frame and then in its rest
frame.

A 15 kg box, initially at rest, slides down a frictionless ramp 10 m high. (a) Compute the velocity of the box as it reach the bottom of the ramp. (b) If it continuously slide horizontally in a horizontal plane with a coefficient of friction μ,-0.15, how far from the bottom of the ramp would it slide before coming into a complete stop? 1.
b. (15 pts) A spacecrft has an initial mass of 1.95 x 106kg. Without its propellant, the spacecran nas a mass of 7.00 X 104 kg. The rocket that powers the spacecrft is designed to eject the Propellant with a speed of 25.0 km/s with respect to the rocket at a constant rate. The Pacecraft is initially at rest in space and travels in a straight line. If the rocket operates for mas = 125 s, how far will the...
12-10. Car A starts from rest at t-0 and travels along a straight road with a constant acceleration of 3 m/s until it reaches a speed of 27 m/s. Afterwards it maintains this speed. Also, when-0, car B located 2000 m down the road is traveling towards A at a constant speed of 20 m/s. Determine the distance travelled by car A when they pass each other. 20 m/s 2000 m 12-11.
