Problem 44P

Problem

(II) Drag-race tires in contact with an asphalt surface have a very high coefficient of static friction. Assuming a constant acceleration and no slipping of tires, estimate the coefficient of static friction needed for a drag racer to cover 1.0 km in 12 s, starting from rest.

Step-by-Step Solution:

Solution 44P: We have to calculate the value of coefficient of static friction whose value depends upon the nature of the surface in contact and independent to applied force, as per the given situation. Step 1 of 3 Concept: Newton’s second law: The net force F acting on an object of mass m produces an acceleration a in that object. Mathematically, F= ma. Frictional force also acts on the surface of the bodies in contact whenever their is relative motion between between the two bodies.
