Tensors and Relativity: Hints 2
- (1) The first two parts should not cause any problems. To explain how the car fits in the garage, draw a spacetime diagram to illustrate what is going on.
- (2) This question is easy, so no hint here!
- (3) First write down the conservation of four- momentum equation for
the collision. Now the trick here is to rearrange this expression in such
a way that when you square it, the angle
is eliminated. This will
give you an expression for
in terms of
and
. To obtain the final expression, you
have to relate
and
to E and E'.
- (4) The first part is straight out of the notes. Have a go at the rest of the
question. A chocolate bar will go to the first person who presents me a
perfect solution!!
