- A subatomic particle moves through the laboratory at 0.90c. Laboratory experimenters measure its lifetime, from creation to annihilation, to be 2.3 ps (1 ps = 1 picosecond = 10-12 s). According to the particle, how long did it live?A 1 km spacecraft is racing towards the Sun at 0.75c. Using equations given in class, calculate the spacecraft length you measure from Earth. Treat Earth as not moving compared to the spacecraft's motion of 0.75 c.Show steps of calculation without using a calculator.
- If a m = 87.5 kg person were traveling at v = 0.992c, where e is the speed of light, what would be the ratio of the person's relativistic kinetic energy to the person's classical kinetic energy? kinetic energy ratio: What is the ratio of the person's relativistic momentum to the person's classical momentum? momentum ratio:A spaceship leaves Earth traveling at 0.60 c. A second spaceship leaves the first at a speed of 0.90 c with respect to the first.

Stellar system Q2, which lies in the same direction in space but is closer to us, is moving away from us at a speed 0.492c. What multiple of c gives the speed of Q, as measured by an observer in the reference frame of Q;? Number UnitsA particle known as a pion lives for a short time before breaking apart into other particles. Suppose a pion is moving at a speed of 0.990c, and an observer who is stationary in a laboratory measures the pion's lifetime to be 2.6 × 10-8 s. (a) What is the lifetime according to a hypothetical person who is riding along with the pion?
