Explanation:

First find the displacement in the x direction:

dₓ = 449 cos 66° + 1112 cos 169° + 1571 cos 26°

dₓ = 182.6 − 1091.6 + 1412

dₓ = 503 km

Next, find the displacement in the y direction:

dᵧ = 449 sin 66° + 1112 sin 169° + 1571 sin 26°

dᵧ = 410.2 + 212.2 + 688.7

dᵧ = 1311 km

The magnitude is:

d² = dₓ² + dᵧ²

d² = (503)² + (1311)²

d = 1404 km

The angle is:

tan θ = dᵧ / dₓ

tan θ = 1311 / 503

tan θ = 2.61

θ = 69°

1404 km and 69° north of east from New Orleans is approximately Toledo.

A passenger on a Ferris wheel moves in a vertical circle at a constant speed. Are the forces on her balanced?

vovikov84 [41]

C. The force is a constant change, because her position on the Ferris wheel will constantly change. I believe this is the answer, but use sources to double check. I might use different vocab. then your teachers.

A soccer player takes a corner kick, lofting a stationary ball 30.0° above the horizon at 18.0 m/s. If the soccer ball has a mas

Radda [10]

Answer:

change in momentum, $\Delta p=7.65 \,kg.m.s^{-1}$

$\Delta p_x= 6.6251 \,kg.m.s^{-1}$

$\Delta p_y= 3.825 \,kg.m.s^{-1}$

Average Force, $F=144.3396\,N$

$F_x=125.0018\,N$

$F_y=72.1698\,N$

Explanation:

Given:

angle of kicking from the horizon, $\theta= 30^{\circ}$

velocity of the ball after being kicked, $v=18 m.s^{-1}$

mass of the ball, $m=0.425\, kg$

time of application of force, $t=5.3\times 10^{-2}\,s$

We know, since body is starting from the rest

$\Delta p=m.v$ .....................(1)

$\Delta p=0.425\times 18$

$\Delta p=7.65 \,kg.m.s^{-1}$

Now the components:

$\Delta p_x= 7.65\times cos 30^{\circ}$

$\Delta p_x= 6.6251 \,kg.m.s^{-1}$

similarly

$\Delta p_y= 7.65\times sin 30^{\circ}$

$\Delta p_y= 3.825 \,kg.m.s^{-1}$

also, impulse

$I=F\times t$ .........................(2)

where F is the force applied for t time.

Then from eq. (1) & (2)

$F\times t=m.v$

$F\times 5.3\times 10^{-2}= 7.65$

$F=144.3396\,N$

Now, the components

$F_x=144.3396\times cos 30^{\circ}$

$F_x=125.0018\,N$

$F_y=144.3396\times sin 30^{\circ}$

$F_y=72.1698\,N$

A sound wave travels in air toward the surface of a freshwater lake and enters into the water. The frequency of the sound does n

Shkiper50 [21]

Answer:

Explanation:

velocity of sound in air at 20⁰C is 343 m /s

velocity of sound in water at 20⁰C is 1481 m /s

The wavelength of the sound is 2.86 m in the air so its frequency

= 343 / 2.86 = 119.93 .

This frequency of 119.93 will remain unchanged in water .

wavelength in water = velocity in water / frequency

= 1481 / 119.93

= 12. 35 m .

What is the average speed of a kangaroo that hops 60 m in 5 s ?

jok3333 [9.3K]

The formula for average speed is
$v_{avg}= \frac{total distance}{total time}$
So we can just substitute our data.
$v_{avg}= \frac{60}{5}=12 \frac{m}{s}$ - its the result
