2. Particle A with mass 9.0 [kg] is at rest relative to the lab frame. What isthe particle's energy and momentum as measured by a rocket frame moving to the +r-direction with speed 0.80 relative to the lab frame?A. E = 9.0 [kg), p, = 7.2 (kg]В. Е — 9.0 [kg], р, — —7.2 [kg]C. E = 15 (kg], Pr =12 [kg]D. E = 15 [kg), Pr =-12 (kg]3. A laser pointer pulses out violet light with frequency, 4.20 x 1014 [m-1].How much energy does each laser photon carry?A. 2.78 x 10-19 (kg]В. 9.28 х 10-28 [kg|(kg]D. 5.26 x 10-57 (kg]С. 1.58 х 10-48

According to Bartleby policy I am doing question 2 only please post the question 3 on another thread

What is the particle's energy and momentum as measured by a rocket frame moving to the +r- direction with speed 0.80 relative to the lab frame? A. E = 9.0 (kg), P. = 7.2 [kg] B. E = 9.0 [kg]. Pz -7.2 (kg] 12 (kg] = C. E = 15 (kg), Pr = D. E = 15 (kg), P. = -12 [kg]
