MP Special relativity hints

5. v= root of (1-1/DF2)

6. DF =total E/rest E =2.6. use this to get v ; root of (1-1/DF2) .923c p=DF mv= 2.6(m).923c

7A find DF first p=DF(mv)

C total energy id DFmc2

D rest energy= mc2

E K=(DF-1) mc2

8. C the DF for .4c is 1.09 the DF for .8c is 1.66. this is less than double as much

9. A A proton (with a rest mass m=1.67×10−27kg) has a total energy that is 6.00 times its rest energy.

What is the kinetic energy Ek of the proton?

Express your answer in billions of electron volts to three significant figures.

Solution. Recall that Kinetic energy is the difference between total energy and rest energy. Therefore the K is 5mc2. To covert to eV remember to divide by 1.6x10-16 J/eV.

4.7 GeV

B If the DF is 6, you can find the speed using the rearranged DF equation root of (1-1/DF2)

Once you have v, the relativistic p is mv times DF

V=.986c p= 6xmv = 2.96x 10-18.

C the speed is .986c
