W^2 = 2 A 8 where A is the angular acceleration.
(3w)^2 = 2 A R where R is the number of revolutions.
Note that you are asked for the additional revolutions.

An airplane is heading due south at a speed of 430 km/h . A wind begins blowing from the northwest at a speed of 85.0 km/h (aver
Igoryamba

Answer:

It should fly 8° to west of south at 430km/h

Explanation:

According to the diagram. X components for both velocities must have the same magnitude in order to get the resultant velocity due south.

V_{w}*cos(45) = V_{A}*sin(\alpha )   Solving for α:

α = 8.03°

Suppose that Lisa walks her dog around the block for a little exercise. The block is 1 mile around. If she walks around the bloc
Alina [70]

Displacement is defined as the net distance traveled through the entire trip. That is to say, if you compared where you are at the end of the walk to where you were at the start, the displacement is the distance between those two points.


Distance doesn't compare the two end points. It just counts the total distance you've walked throughout your trip.


Lisa walks once around the block. She starts and ends at the same place. Her displacement is therefore 0 m.


But she has walked 1 mile throughout the trip. Her distance walked is therefore 1 mile.

The operator of a space station observes a space vehicle approaching at a constant speed v. The operator sends a light signal at
GenaCL600 [577]

Answer:

The speed of the light signal as viewed from the observer is c.

Explanation:

Recall the basic postulate of the theory of relativity that the speed of light is the same in ALL inertial frames. Based on this, the speed of light is independent of the motion of the observer.
