suppose that you are an accident investigator and you are asked to figure whether or not the car was speeding before it crashed through the rail of the bridge and into the mudbank as shown. the speed limit of the bridge is 55mph=24m/s. what is your conclusion.the picture shows the area where the car crashed and its vertical is 4.9 and its horizontal is 24m

how long does it take to fall 4.9m?

4.9=1/2 9.8 t^2

t=1sec

speedhorizontal=24/1 m/s

But it crashed through a rail first, so the speed before the crash must have been faster.

I don't believe in using pyschics to invdestigate accidents, although they do it on TV.

Do you mean physics?
