Could be very slow since they’re basically going against the current which is hard so will be going slow
Define an x-y coordinate system such that
The positive x-axis = the eastern direction, with unit vector
.
The positive y-axis = the northern direction, with unit vector
.
The airplane flies at 340 km/h at 12° east of north. Its velocity vector is
The wind blows at 40 km/h in the direction 34° south of east. Its velocity vector is
The plane's actual velocity is the vector sum of the two velocities. It is
The magnitude of the actual velocity is
v = √(121.1615² + 306.0473²) = 329.158 km/h
The angle that the velocity makes north of east is
tan⁻¹ (306.04733/121.1615) = 21.6°
Answer:
The actual velocity is 329.2 km/h at 21.6° north of east.
Some basic reasons:
you can make more friends
you can participate in physical exercise
you can learn a new sport/skill (skateboarding)
Answer:
Elbow Lake
Explanation:
An oxbow lake is a stagnant lake that forms along a winding river due to soil erosion resulting in an abandoned stream, cut off from the river. An oxbow lake begins as meander or a curve in a river after some time, the curve becomes larger as a result of erosion and hydraulic action.
Answer:
KE = 1/2mv^2
KE = 1/2(24)(3^2)
KE = 12(9)
KE = 108 J
