Here is the questions: A box of mass m= 10 kg is sitting on the floor of a truck as the truck rounds a curve to the left of radius 15 m at 12 m/s. There is friction between the box and the floor of the truck with mus= .45 and muk = .20. 1. Does the box slide? 2. If the box slides, in what direction and with what acceleration? 3. If the box doesn't slide, what would the coefficient of static friction be in order for it to slide?
