Homework Statement
The total weight of the go-cart and driver is 1068N. The location of their combined center of mass is shown in attachment. The rear wheen exert a 106.7 N horizontal force together on the track. Neglect horizontal force on the front wheels.
a) What is go carts acceleration? [SOLVED MYSELF]
b) What are the normal forces exerted on the tires at A and B?
Homework Equations
Moment around centre of mass.
The Attempt at a Solution
NA+NB-W = 0 (where NA and NB is normal force acting on the tires)
Moment around CM in clockwise direction
NA*(0.4064)+F*(0.381)-NB*(1,1176) = 0
solving for NA and NB I get
My answer; NA = 756,52 N NB = 485 N, which is wrong according to the book.
I don't know what is wrong. Please help.
