A 5.00 x 10^4 kg space probe is travelling at a speed of 14000 m/s through deep space. Retrorockets are fired along the line of motion to decrease the probe's speed. The retrorockets generate a force of 4.00 x 10^5 N over a distance of 2600 km. What ..
A proton moves perpendicular to a uniform magnetic field, B, at 1.6 multiplied by 107 m/s and experiences an acceleration of 1.8 multiplied by 1013 m/s2 in the positive x direction while its velocity is in the positive z direction. Find out the magni..
