The bearing shows the angle from north to the line (c), you want to see the angle inside the triangle so that will be 90-[bearing].
<span>a=42 (42 mph wind blowing north) </span>
<span>A= 90-74.9 </span>
<span>A= 15.1 degrees </span>
<span>Ground speed is the speed the plane is going including the wind. </span>
<span>ground speed = c </span>
<span>Airspeed = b </span>
<span>You have the angle, and you have the "Opposite" and want to find the "Hypotenuse". </span>
<span>SOH CAH TOA </span>
<span>Sin x = Opp/Hypot </span>
<span>Sin(15.1) = 42/c </span>
<span>c = 42/Sin(15.1) </span>
<span>c = 161.53 </span>
<span>Ground speed of the plane is 161.53 mph </span>
<span>Airspeed = b </span>
<span>Tan x = Opp/Adj </span>
<span>Tan (15.1) = 42/b </span>
<span>b = 42/Tan(15.1) </span>
<span>b = 161.53 </span>
<span>Airspeed = 161.53 mph </span>
<span>(so the answer is ground speed of 161.53mph)</span>
Answer:
the correct statement is
* atoms cannot be created or destroyed
Explanation:
The Datlon atomic model was proposed in 1808 and represents atoms as the smallest indivisible particle of matter, they were the building blocks of matter and are represented by solid spheres.
Based on the previous descriptive, the correct statement is
* atoms cannot be created or destroyed
The force is going which ever way the person kicks the ball.
Answer:
32500 kg m/s east, 42500 kg m/s west. Second car has larger momentum
Explanation:
The momentum of an object is given by
p = mv
where
m is the mass
v is the velocity
For the first car, m = 500 kg and v = 65 m/s east, so the momentum is
east
For the second car, m = 500 kg and v = 85 m/s west, so the momentum is
west
By comparing the two momentum, we see that the second car has larger momentum.
