The plane's heading is 4.61 degrees south of east, which is the direction the pilot needs to steer the plane in order to reach her objective and the trip takes 1.83 hours.
<h3>What is the distance?</h3><h3 />
Distance is a numerical representation of the distance between two objects or locations.
The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Let the pilot's heading be theta south with an east direction. The resultant the velocity will be;
Hence the direction of the plane heading is 4.61 degrees south of east
b)
The resultant speed of the plane(V)is found as;
Hence, the trip takes 1.83 hours.

a. subduction.
Explanation:
A subduction zone is a zone where the oceanic crust dives beneath the continental crust.
- Subduction zones are typical features of convergent margins where two plates pulls together.
- They are formed by continent-oceanic covergence and ocean - ocean covergence.
- In oceanic - continent convergence, the denser oceanic crust slides under the continental crust because it is denser than the mantle below.
- In oceanic - oceanic crust convergence, either of the plate slides under the other into the mantle.
- Trenches, volcanoes, earthquakes are typical geologic features associated with them.

The tail consists of gas and dust that can extend hundreds of millions of kilometers away from the coma. Most comets actually have 2 tails: a plasma tail made of ionizedgas, and a dust tail made of small solidparticles. Comet tails point away from the Sun.
Initial angular velocity = 0 (starting from rest)
Final angular velocity = 30 rad/s
Distance traveled = (20 rev)*(2π rad/rev) = 40π rad
Let the angular acceleration be α rad/s².
Then
(30 rad/s)² = (0 rad/s)² + 2*(α rad/s²)*(40π rad)
α = 3.58 rad/s²
Answer: 3.58 rad/s² (nearest hundredth)
Answer:
Time elapsed = 2.856
SECOND ROCK HAS FASTER SPEED
Explanation:
This can be achieved in 2 ways, and it is clear from the careful study that the travel time is attributed to the time required to cross the path above the bridge by the 2nd stone i.e.
14 = 9.8 * t
t = 1.428 sec and
time between 2 splash = 2 * 1.428 = 2. 857 sec
2nd way
let time for 1st spalsh be t and
second splash be t1.
from equation of motion
so 60 = 14t + 0.5 * 9.8 * t * t
4.9 t^2 + 14t -60 = 0
On solving, we get t = 2.351 sec
for t_1, we have some extra time, which can be divided into t2 and t3.
14 = 9.8 * t2
t2 = 1.428 sec
total time taken by 2 is
T = 1.428 + 1.428 + 2.351
so we get t_1 = 5.207 sec
time elapsed is = T - t
= 5.207 - 2.351
Time elapsed = 2.856
