Question
3/190 Car B is initially stationary and is struck by car A,
which is moving with speed v. The cars become en-
tangled and move with speed u' after the collision.
The mass of car A is m and that of car B is pm,
where p is the ratio of the mass of car B to that of
car A. If the duration of the collision is At, express
the common speed u' after the collision and the av-
erage acceleration of each car during the collision
in terms of u, p, and At. Evaluate your expressions
for p
