A man attempts to push a 19.8 kg crate across a warehouse floor. He slowly increases the force until the crate starts to move at
VARVARA [1.3K]

Answer:

 μ = 0.18

Explanation:

Let's use Newton's second Law, the coordinate system is horizontal and vertical

Before starting to move the box

Y axis

     N-W = 0

     N = W = mg

X axis

     F -fr = 0

     F = fr

The friction force has the formula

     fr = μ N

     fr =  μ m g

At the limit point just before starting the movement

     F = μ m g

     μ = F / m g

calculate

      μ = 34.8 / (19.8 9.8)

    μ = 0.18

If the average speed of a person was 1.2 meters/second, does this mean that their speed was exactly 1.2 meters/second the whole
alexandr1967 [171]

Average speed is defined by the following formula

v = \frac{D}{t}

here

D = total distance that an object move from its initial position to final position

t = total time of the motion

so here we will say that there is no such relation between initial or final speed or we can say maximum or minimum speed of object with average speed of object.

We only need to find the total distance and total time of motion in order to find the average speed

here we can see many examples like let say an object moves with speed v1 for time t1 and then with speed v2 for time t2 then here average speed is given as

d = v_1 t_1 + v_2t_2

since we know that distance covered is product of speed and time

that's why we used above equation for finding total distance

now the average speed will be

v_{avg} = \frac{v_1t_1 + v_2 t_2}{t_1 + t_2}

so this is how we can find the average speed for above motion

so average speed is always between maximum and minimum speed any value in-between.

It is neither the maximum value nor it is minimum value

0.318 cm. What is the ideal mechanical advantage?
vodomira [7]

The ideal mechanical advantage will be 8.017. The ideal mechanical advantage value may be grater than the actual value of mechanical advantage.

<h3>What is mechanical advantage ?</h3>

Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtained efficiency of  forces in levers and pulley.

The ideal mechanical advantage is found as;

\rm IMA = \frac{d \pi}{l} \\\\ \rm IMA = \frac{0.812 \times  \pi}{0.318} \\\\ IMA=8.017

The ideal mechanical advantage will be 8.017.

To learn more about the mechanical advantage, refer to the link;
