Question

Calculate the maximal friction force for a parked car between the rubber tires and a wet street. Assume the car’s mass is 1600 kg with a weight of 15680 N. The static friction coefficient for rubber and wet asphalt is μs=0.8.

Answer 1

Answer:

$Fr=12544N$

Explanation:

1. Find the equation of eht maximal friction force:

The maximal friction force is given by the equation $Fr=usmg$, where μs is the static friction coefficient, m is the car´s mass and g is the gravitational force.

2. Replace values in the equation to find the answer:

$Fr=0.8*1600kg*9.8\frac{m}{s^{2}}$

$Fr=12544N$
