Problem 6.13 The point of this question is to compare rest energy and kinetic energy at high speeds. An alpha particle (a helium nucleus) is moving at a speed of 0.9998 times the speed of light. Its mass is 6.40 × 10-27 kg. (a) What is its rest energy?

E = 5.76×10^-10 J

Explanation: rest energy formula is given below as

E = mc²

m = mass of object = 6.40×10^-27 kg

c = speed of light = 3×10^8 m/s

E = 6.40×10^-27 × (3×10^8)²

E = 6.40×10^-27 × 9×10^16

E = 57.6 ×10^-11

E = 5.76×10^-10 J

t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanatio
