- How much energy is required to accelerate a golf ball of mass 0.046 kg initially at rest to a speed of 0.75c?A spaceship approaching an asteroid at a speed of 0.77c launches a rocket forward with a speed of 0.27c relative to the spaceship. At what factor of the speed of light c is the rocket approaching the asteroid as measured by an astronaut on the asteroid?A particle is accelerated from 0.975c to 0.992c as measured in a laboratory reference frame. This is a change in speed of only 1.7% and the ratio of the velocities is 1.017 (as measured in the lab frame). What is the ratio of the particle momentum when moving at 0.992c as compared to when it was moving at 0.975c? This ratio should be expressed as a decimal number. P2 P₁
