Centripetal and Centrifugal force Question?
A car of mass 1,350kg and with a wheelbase width of 1.5m has a load of 375kg on a roof rack so that the combined centre of mass is 0.9m above the ground. Calculate the minimum speed at which the car may overturn when travelling around a horizontal curve of radius 115m on a level road.

I really dont know how to go about this question, not a fan of worded ones, answer isnt needed, just mainly the working out so i can fully understand it
Thanks 
First, you've got a center of (1725kg of) mass 0.9m above ground between (presumably half way between) 2 supports 1.5m apart.
You need to figure out what horizontal force will tip the object over.
Then calculate what speed around a 115m radius curve will produce this amount of horizontal force.
Bingo
