Explosions Flashcards
1
Q
What must happen in terms of momentum in a collision?
A
total initial momentum = 0
therefore exploding object must have a momentum = 0
they have to move at equal and opposite of momentum
2
Q
How can this be tested?
A
trolleys with spring
trolleys A and B push each other apart
two blocks placed so the trolleys hit them at the same moment
= momentum, the ratio of their speed should be the inverse of the amss ratio
if A travels twice as far as B, then A must have half the mass of B
