two soccer players, mary and jane, begin running from nearly the same point at the same time. mary runs in an easterly direction

at 4.43 m/s, while jane takes off in a direction 60.2o north of east at 5.07 m/s. how long is it before they are 24.7 m apart? what is the velocity of jane relative to mary? enter first the x-component and then the y-component. how far apart are they after 4.08 s?

The time taken before the two soccer players are 24.7 m apart is 3 seconds.

Velocity of Jane relative to marry is 4.4 m/s in y-direction and 6.95 m/s in x direction.

The distance between Jane and Mary after 4.08 seconds is 33.58 m.

<h3>Resultant velocity of Mary and Jane</h3>

Vertical component of the velocity;

Jane: Vy1 = V sinθ

Vy1 = 5.07 m/s  x  sin(60.2)

Vy1 = 4.4 m/s

Horizontal components of the velocity;

Jane: Vx1 = V cos θ

Vx1 = 5.07 m/s  x  cos60.2

Vx1 = 2.52 m/s

mary: Vx2 = 4.43 m/s

total horizontal components of the velocity = 4.43 m/s + 2.52 m/s = 6.95 m/s

<h3>Resultant velocity</h3>

V = √Vy² + Vx²

V = √(4.4² + 6.95²)

V = 8.23 m/s

<h3>Time taken before they are 24.7 m apart</h3>

t = 24.7 m / 8.23 m/s

t = 3 seconds

Velocity of Jane relative to marry is 4.4 m/s in y-direction and 6.95 m/s in x direction.

<h3>Distance between Jane and Mary after 4.08 seconds</h3>

d = vt

d = 8.23 m/s  x 4.08 s

d = 33.58 m

If the work done to stretch an ideal spring by 4.0 cm is 6.0 j, what is the spring constant (force constant) of this spring?
Alisiya [41]

Answer:

The spring constant is 3750 N/m  

Explanation:

Use the following two relationships:

(Work) = (Force) x (Displacement)

(Force) = (Spring constant) x (Displacement)

=>

(Spring constant) = (Force) / (Displacement) = (Work) / (Displacement)^2

(Spring constant) = 6.0 kg.(m^2/s^2) / 0.0016 m^2 = 3750 N/m

The spring constant is 3750 N/m

Why do we tend to attribute others' negative behaviors to dispositions over situational factors?
miskamm [114]

Answer:

Because you have a greater understanding of the mentality and conduct of individuals you care about, you are better able to understand their perspective and are more likely to recognize possible situational factors for their behavior.
