A spaceship is moving in a straight line at 36,000 miles per socond. Suddenly it accelerates at a(t) = 18t miles per second squared. Assume that the speed of light is 186,000 miles per second and that relativistic effects do not influence the velocity of the spaceship. How long does it take the ship to reach the speed of light and how far does it travel during that time?
An electron moves with a constant horizontal velocity of 3.0 x 100 m/s and no initial vertical velocity as it enters a deflector inside a TV tube. The electron strikes the screen after traveling
