Question

I just need help with part C please! I'm struggling! Thank you.

a) If half of the weight of a flatbed truck is supported by its two drive wheels, what is the maximum acceleration (in m/s^2) it can achieve on dry concrete where the coefficient of kinetic friction is 0.7 and the coefficient of static friction is 1.

The answer is 4.9 m/s^2.

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

The answer is No.

c) If the truck has 4-wheel drive and the cabinet is wooden, what is its maximum acceleration in (m/s^2)?

Answer: ???

Will it slip? Yes or No?

Watch Wizards of Wave w6ch 6 2063 - PHY The OpenStax arch this book Q O Back As seen in Table 5.1, the coefficients of kinetic friction are less than their static counterparts. That values of u in Table 5.1 are stated to only one or, at most, two digits is an indication of the approximate description of friction given by the above two equations. System Ms Static friction Mx Kinetic friction Rubber on dry concrete Rubber on wet concrete Wood on wood Waxed wood on wet snow Metal on wood Steel on steel (dry) Steel on steel (oiled) 0.05 0.3 0.03 0.04 Teflon on steel 0.04 Bone lubricated by synovial fluid 0.016 0.015 Shoes on wood 0.9 0.7 Shoes on ice 0.1 0.05 Ice on ice 0.03 Steel on ice 0.02 Table 5.1 Coefficients of Static and Kinetic Friction The equations given earlier include the dependence of friction on materials and the normal force. The direction of friction is always opposite that of motion, parallel to the surface between objects, and perpendicular to the normal force. For example, if the crate you try to push with a force parallel to the floor has a mass of 100 kg, then the man w
