If half of the weight of a flatbed truck is supported by

Question

Solve the all parts of given question:

Part 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 dry concrete where the coefficient of kinetic friction is 0.7 and the coefficient of static friction is 1.

= ___ m/s²

Part B: Will a metal cabinet lying on the wooden bed of the truck slip if it accelerates at this rate where the coefficient of kinetic friction is 0.3 and the coefficient of static friction is 0.55?

Part C: What is the maximum acceleration for the case that the truck has four-wheel drive, and the cabinet is wooden?

= _____ m/s²

Please help, completely confused!! Give steps if possible.
