the proper lifetime of a certain particle is 100.0 ns. a) how long does the particle live in the laboratory frame if it moves at v = 0:960c? b) how far does it travel in the laboratory during that time (still in the laboratory frame)? c) what is the distance traveled in the laboratory according to an observer moving with the particle?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
