The flatbed truck is traveling at the constant speed of 60 km/h up the 15‐percent grade when the 100‐kg crate which it carries is given a shove which imparts to it an initial relative velocity ˙ x = 3 m / s x˙=3 m/s toward the rear of the truck. If the crate slides a distance x = 2 m measured on the truck bed before coming to rest on the bed, compute the coefficient of kinetic friction μk between the crate and the truck bed.

Blank liquids and gases exert a buoyant force on objects placed in them
