(a) If half of the weight of a flatbed truck is supported by its two drive wheels, what is the maximum acceleration it can achieve on wet concrete where the coefficient of kinetic friction is 0.5 and the coefficient of static friction is 0.7. answer in m/s^2 (b) Answer both of these questions for the case that the truck has four wheel drive and the cabinet is wooden. What is the maximum acceleration in m/s^2? Will it slip
