A 1.0g particle has momentum 400,000kgm/s. What is the particle’s speed in m/s?

Short Answer

Expert verified

400m/s

Step by step solution

01

Given Information

We have given that a 1.0gparticle has momentum 400,000kgm/s.

We have to find the particle’s speed in m/s.

02

Simplify

The momentum in relativity is given by

P=mv1-v2C2

Here

P=400,000kgm/sand

m=1g=1×10-3kg

So, the equation becomes

400,000=1×10-3×v1-v2(3×108)2v=400m/s

Firecracker A is 300m from you. Firecracker B is 600m from you in the same direction. You see both explode at the same time. Define event 1 to be “firecracker A explodes” and event 2 to be “firecracker B explodes.” Does event 1 occur before, after, or at the same time as event 2? Explain.

At what speed, as a fraction of c, is a particle’s kinetic energy twice its rest energy?

Some particle accelerators allow protons1p+2and antiprotons1p-2to circulate at equal speeds in opposite directions in a device called a storage ring. The particle beams cross each other at various points to causep++p-collisions. In one collision, the outcome isp++p-e++e-+γ+γ, where g represents a high-energy gamma-ray photon. The electron and positron are ejected from the collision at0.9999995cand the gamma-ray photon wavelengths are found to be1.0×10-6nm. What were the proton and antiproton speeds, as a fraction of c, prior to the collision?

Firecrackers A and B are 600m apart. You are standing exactly halfway between them. Your lab partner is 300m on the other side of firecracker A. You see two flashes of light, from the two explosions, at exactly the same instant of time. Define event 1 to be “firecracker A explodes” and event 2 to be “firecracker B explodes.” According to your lab partner, based on measurements he or she makes, does event 1 occur before, after, or at the same time as event 2? Explain

A cosmic ray travels 60km through the earth’s atmosphere in 400μs as measured by experimenters on the ground. How long does the journey take according to the cosmic ray?
