Here we go again (yes, this set of questions is starting to feel
like Groundhog Day). You AGAIN wake up in a strange room, and this
time you drop a ball from a height of 2.41 m, and observe that it
hits the floor 0.210 s after you drop it. In this case you suspect
you are in deep space, far from any planet or star, and that your
rocket is accelerating due to the push of its own engines under the
floor. In this case, what must the acceleration of your rocket
be?
54.6 m/s^2
82.0 m/s^2
185.8 m/s^2
109.3 m/s^2
OK, yet another strange awakening in a room with no windows.
This time you drop a ball from a height of 1.92 m and it hits the
floor 0.250 s after you drop it. This time you suspect you are on a
rocket that has just left the surface of the Earth, and is still
not too far above the ground. What do you deduce the rocket s
acceleration to be?
61.5 m/s^2
82.6 m/s^2
51.6 m/s^2
71.3 m/s^2
