Asked by Noe Valencia

You're driving your pickup truck around a curve with a radius of 22meters. A box in the back of the truck is pressed up against the wall of the truck.
-How fast must you drive so that the force of the wall on the box equals the weight of the box?

Answered by drwls
If the centripetal force on the box equals the weight,
V^2/R = g
V = sqrt(R*g) = 14.7 m/s
Answered by Alex
V^2/R = gu
V = sqrt(R*g*u) = 13.133 m/s
u is the coefficent of static friction. Since this is steel on steel, u=0.1
