HW09_#3 Truck The friction between the flatbed of a truck and the 50-kg crate it carries is defined by coefficients of static friction μs=0.30 and kinetic friction μk=0.25. A. For the crate to NOT slip forward, find the minimum stopping distance S which the truck can have from a speed of 70 km/h with constant deceleration. B. If the truck uniformly decelerates in a distance of 50 m from an initial forward speed of 70 km/h, show and describe your numeric proof that the crate would slide on the flatbed. C. Based on the scenario in Part B, find the value (and sign) of the acceleration of the crate relative to the truck. Describe a situation when you have witnessed something like this happening. +9=x suv
