- A baseball pitcher can throw a ball with a speed of 40 m/s. He is in the back of a pickup truck that is driving away from you. He throws the ball in your direction, and it floats toward you at a lazy 10 m/s. What is the speed of the truck?There are two relativistic particles of identical mass m that move towards each other along the same axis. The magnitudes of their momenta are the same. They collide head-on to form a new particle of mass 8m. What were the magnitudes of momenta of the initial particles?. A rocket with a mass of 2.30×1062.30×106 kg has a relativistic kinetic energy of 3.70×10233.70×1023 J. How fast is the rocket moving?
- The velocity of an alpha particle, He2+, with a mass of 6.64×10−27kg changes from v1=(−0.30, 0.45,0.10)c to v2=(−0.50, 0.30, −0.75)c, where c=3×108m/s. Determine the change in the particle’s kinetic energy.(In the kinetic energy formula, do not forget to square the speed of light.)Astrophysics 14 Use Newton's second law, F = dp/dt, and the formula for relativistic momentum, Eq. ( 44), to show that the acceleration vector a = dv/dt produced by a force F acting on a particle of mass m is F (F. v), ymc² Ym where F· v is the vector dot product between the force F and the particle velocity v. Thus the acceleration depends on the particle's velocity and is not in general in the same direction as the force. mv p = /1 – v²/c² = ymv (44) VI -
