1. The problem statement, all variables and given/known data A car collides with a brick wall and comes to rest. A parcel which was on top of the roof at the time becomes detached. It is initially traveling horizontally and it strikes the ground a distance of 12m from the point where it left the car. The parcel is initially 1.5 m above ground. What period of time elapses before the parcel strikes the ground? Estimate the speed of the car just before it collided with the wall? 2. Relevant equations s=ut+1/2at^2 v=u+at v^2=u^2+2as 3. The attempt at a solution i have no idea where to start, ??
