a
of
Science fiction writers imagine a ship in deep space, accelerating at a constant 9.8 m.s ?, which gives the travellers
a sensation similar to the weight they feel on the Earth, where falling objects accelerate at g = 9.8 m.s ?. Starting
from rest (and ignoring effects due to special relativity), how long does it take such a ship to accelerate to 0.1 times
the speed of light c (recalling that c= 3.0+10® m.s-1), and how far does it travel during that time? (Note: 0.1 has only
1 sig fig!)
Answer: The ship travels for
and travels a distance of
4 days, 5 x 10° km
40 days, 5 x 104 km
40 days, 5 x 1010 km
4 days, 5 x 1014 km

You drop a ball, which accelerates downwards with constant acceleration g = 9.8 m.s 2. It falls a distance of 0.50
m to the ground.
The ball hits the ground in
seconds. When it hits the ground, it is travelling at a velocity of m/s. (The up
direction is positive.)

6. One of the potentially confusing things about special relativity is that it shows us that the time measured between two events depends upon your inertial frame of reference. In particular, two events that appear to be simultaneous in one inertial frame may be measured to occur at different times in a different inertial frame. Even more interesting is that Event 1 might occur either before or after (or at the same time as) Event 2, depending upon your reference frame! The proper interpretation of these facts is to say that nothing in physics forces two simultaneous events in one frame to be simultaneous in any other frame. However, what about the order of events when Event 1 CAUSES Event 2? For example, let's consider two events from a game of pool: 1) A cue ball, traveling at 10 m/s, hits the eight ball (of mass equal to the cue ball). An elastic collision transfers all the linear momentum of the cue ball to the eight ball. 2) 0.1 seconds later, the eight ball sinks in a corner…
