You are working with a 3 T MRI scanner with maximum gradient strength of 40 mT/m in all 3 axes (x, y,z). Your acquisition uses maximum gradient strength to minimize the duration of the data acquisition window. When the Gx is the only gradient that is turned on, what is the rotation frequency for spins located at x=5cm, y=5cm? The gyromagnetic ratio is γ=42.576 MHz/T

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds
