our lab partner wears a new pair of sneakers to lab and, rather than performing the required experiments, you decide to measure

Dafna1 [17]

Answer:

The coefficient of static friction between your partner and the floor is 0.55

Explanation:

Given:

Mass $m = 59$ Kg

Frictional force $F_{s} = 318.3$ N

From the formula of frictional force,

$F_{s} = \mu_{s} mg$

Where $\mu _{s} =$ coefficient of static friction, $g = 9.8 \frac{m}{s^{2} }$

Put the above values and find the coefficient of static friction.

$318.3 = \mu_{s} \times 59 \times 9.8$

$\mu_{s} = 0.55$

Therefore, the coefficient of static friction between your partner and the floor is 0.55

A reasonable walking speed is _____. A. 0.02 m/s B. 0.2 m/s C. 2 m/s D. 20 m/s

statuscvo [17]

I am gonna have to say A 0.02 because 2 meters a second is way too fast 0.2 is a little more than reasonable and if 2 meters a second is too fast then 20 is off so A. should be most reasonable
