A seagull flies at a velocity of 9.00 m/s straight into the wind. (a) if it takes the bird 20.0 min to travel 6.00 km relative t

enot [183]

Here we will the speed of seagull which is v = 9 m/s

this is the speed of seagull when there is no effect of wind on it

now in part a)

if effect of wind is in opposite direction then it travels 6 km in 20 min

so the average speed is given by the ratio of total distance and total time

$v_{avg} = \frac{6000}{20*60}$

$v_{avg} = 5m/s$

now since effect of wind is in opposite direction then we can say

$V_{net} = v_{bird} - v_{wind}$

$5 = 9 - v_{wind}$

$v_{wind}= 4 m/s$

Part b)

now if bird travels in the same direction of wind then we will have

$v_{net}= v_{bird} + v_{wind}$

$v_{net} = 9 + 4 = 13 m/s$

now we can find the time to go back

$time = \frac{distance}{speed}$

$time = \frac{6000}{13}$

$time = 7.7 minutes$

Part c)

Total time of round trip when wind is present

$T = t_1 + t_2$

$T = 20 + 7.7 = 27.7 min$

now when there is no wind total time is given by

$T = \frac{6000}{9} + \frac{6000}{9}$

$T = 22.22 min$

So due to wind time will be more

Imagine that you have two marbles on a table. You roll one marbles towards another. When the marble collide, the marble at rest

Alika [10]

Because that's called friction. When to things collide it causes friction which makes them stop rolling>

An explosion occurs 34 km away. the time it takes for its sound to reach your ears, traveling at 340 m/s, is

Murrr4er [49]

Let's convert the distance in meters first:
$d=34 km=34000 m=3.4 \cdot 10^4 m$
The sound wave travels at speed
$v=340 m/s$
So we can use the basic relationship between space, time and velocity to calculate the time it takes for the sound to reach our ears:
$t= \frac{S}{v}= \frac{3.4 \cdot 10^4 m}{340 m/s}=100 s$

A 29.0 kg beam is attached to a wall with a hi.nge while its far end is supported by a cable such that the beam is horizontal.

babunello [35]

26.10 N is the vertical component of the force.

Rx represents the Horizontal component of force

Ry represents The Vertical component of force

According to the given diagram

Rx - Tcosθ = 0

Rx = Tcosθ

And,

Ry + Tsinθ = mg

Ry = mg - Tsinθ

The horizontal component of force =The Vertical component of force

Rx = Ry

Tcosθ = mg - Tsinθ

T(cosθ + sinθ) = 29 × 9.8 = 284.2 N

T√2 cosθ = 284.2 N

T × √2 ×0.544 = 284.2 N

T × 0.769 = 284.2 N

T = 370 N (app)

So,

Ry = 284.2 - 370 (sin 57°)

= 284.2 - 310.3 = -26.10 N

Hence, 26.10 N is the vertical component of the force exerted.
