Uniform circular motion

[Neil]

A question on circular motion i wasn't able to figure without knowing the mass of the body. Can anbody post the ans + procedure. Thanx

A car travels over a humpback bridge of radius of curvature 45m. Calculate the max. speed of the car if it's road wheels are to stay in contact with the bridge. Assume g=10ms-2

[Tide]

What is the centripetal acceleration? :-)

Welcome Neil !
As you can see :
Can anbody post the ans

No. :mad:

...+ procedure.
It will be possible to provide you hints about that :approve:

[humanino]

You must assume that the car reached its maximum speed, therefore this speed being constant. Then use Tide's hint and the value given for g.

[Nenad]

here is a hint, and its a BIG one, draw a free body diagram, and use this formula F = \frac{mv^2}{r}
