ok a tunnel is 4 m wide and 4 m high.
/|\
/ | \
/__|__\
4m
and a truck is 2 m wide and has to drive through it (Through the middle). what is the maximum height that the truck can be?
if your can help PLEASE do!! even give a hint :P
anyone get it????
Hi Trish:
I presume what they're asking is if you have a tunnel that is a parabola.
If that is right, then you can write the equation of the tunnel, and then you can find the maximal height of the truck. Do you think this is the problem?
