The pilot of rocket A, moving at a velocity of 0.8c relative to earth, observes a second rocket B that moves along the same line approaching him from behind at 0.7c. What does an observer on earth measure for the second rocket’s velocity?
For observer S, a meter stick at rest makes an angle of 25 degrees with the x-x’ axis. How long is that meter stick for S? An observer S’ who moves along the y-y’-axis at 0.5c sees what length and what angle for the meter stick?

A space vehicle is traveling at 4300 km/h relative to earth when the exhausted rocket motor (mass 4m) is disengaged and sent backward with a speed of 82 km/h relative to the command module (mass m).a) What is the speed of the space vehicle after the engine has separated relative to earth? b) What is the speed of the command module relative to earth just after the separtaion.

A fireworks rocket is moving at a speed of v = 45.7 m/s. The rocket suddenly breaks into two pieces of equal mass, which fly off with velocities v1 at an angle of theta1 = 30.7° and v2 at an angle of theta2 = 59.3° as shown in the drawing below.

A rocket sits initially at rest on the surface of the earth, until it begins burning its engines. While burning its engines, it accelerates upward at 30.0 m/s2 for 30.0 s. It then runs out of fuel and continues ascending to its maximum height in free fall. Ignoring air resistance, (i) what is the rocket’s maximum altitude, and (ii) how much time passes from liftoff to reaching its maximum altitude?

When the rocket is on earth and lifting off and burning fuel, which of the following is or are conserved? Mark all that apply and provide a brief 1-2 sentence justification of your choices.  Momentum of the rocket  Mechanical energy of the rocket  Momentum of the rocket + exhaust + Earth system  Mechanical energy of the rocket + exhaust + Earth system When the rocket no longer burns fuel (but is still near Earth), which of...

A rocket is launched from rest and reaches a position of (65m, 185m) and a velocity of (195m/s, 555m/s) when it runs out of fuel. From this time, tbo, it flies a projectile motion path. Find the maximum height above the ground the rocket achieves after running out of fuel Find the time t and position x of the rocket when it hits the ground.
