Question

A rocket cruises past a laboratory at 0.950 !! 10^6 m/s in the positive x-direction just as a proton is launched with velocity (in the laboratory frame) v = (1.76 !! 10^6i + 1.76 !! 10^6j) m/s. What is the proton's speed in the laboratory frame? Express your answer with the appropriate units. v_l = Part B What is the angle from the y-axis of the proton's speed in the laboratory frame? Express your answer with the appropriate units. theta_l = Part C What is the proton's speed in the rocket frame? Express your answer with the appropriate units.

Step 1

76 \times 10^6 \text{ m/s}, 1.76 \times 10^6 \text{ m/s})\) The magnitude of the velocity vector is given by: \[ |v| = \sqrt{(1.76 \times 10^6)^2 + (1.76 \times 10^6)^2} \] \[ |v| = \sqrt{3.1256 \times 10^{12} + 3.1256 \times 10^{12}} \] \[ |v| = \sqrt{6.2512 Show more…
