Suppose a rocket ship is traveling in deep space accelerates with constant acceleration of 9.8 m/s^2. If it starts from rest, how long will it take to acquire a speed that is one-tenth the speed of light (light travels at 3.0x10^8 m/s)?
Peak values for a neodymium-glass laser are 600 joules for 1 nanosecond. If the cross-section of the laser beam is 1 cm2, what are the maximum values of E and B? (Β΅0 = 4p Β΄ 10-7 T-m/A)
A rocket is moving away from the solar system at a speed of 6.0x10^3 m/s. It fires its rocket engine, which ejects exhaust with relative velocity 3.0x10^3 m/s. The mass of the rocket at this time is 4.0x10^4 kg, and it experiences an acceleration of 2.0 m/s^2. What is the velocity of the exhaust relative to the solar system? (B) At what rate was the exhaust ejected during the firing?
