Does the spaceship travel before the alarm clock sounds : An alarm clock is set to sound in 20 h. At t = 0, the clock is placed in a spaceship moving with a speed of 0.72c (relative to Earth). What distance, as determined by an Earth observer, does the spaceship travel before the alarm clock sounds?

Model rocket is launched from rest with upward acceleration : A model rocket is launched from rest with an upward acceleration of 6.00 m/s^2 and, due to a strong wind, a horizontal acceleration of 1.50 m/s^2. How far is the rocket from the launch pad 6.00s later when the rocket engine runs out of fuel?

Radioactive dating method is used experimental error : When any radioactive dating method is used, experimental error in the measurement of the sample's activity leads to error in the estimated age. In an application of the radiocarbon dating technique to certain fossils, an activity of 0.10 Bq per gr..
