An airplane travels at 150 km per h toward the northeast what is the northern component of its velocity?
The northern component of the velocity can be found by multiplying the velocity by the cosine of the angle it makes with the north direction. Since the airplane is moving northeast, which is 45 degrees from north, the northern component velocity would be 150 km/h * cos(45°) ≈ 106 km/h.
Does the velocity of a falling object increase or decrease?
The velocity of a falling object increases as it falls due to the acceleration of gravity acting on it. As the object falls, it gains speed and accelerates toward the ground until it reaches a constant velocity known as terminal velocity.
Why does velocity of an arrow change as it travels toward the target?
A velocity vector would include both a speed and direction. Wind (air) resistance will affect the speed component, slowing down the arrow as time passes. Gravity will pull it downward at a constant acceleration of 9.8 m/s2. This means that the downward component of the velocity will increase with time. Wind, of course, could also throw the arrow off course.
When gravitational forces and air resistance equalize on an object that is falling toward earth and the object stops accelerating its velocity is called?
In that case, the object is said to have achieved terminal speed.
What is the light ray that travels toward a reflective surface?
An incident light ray is a light ray that travels toward a reflective surface. When this ray hits the surface, it may be reflected, refracted, or absorbed, depending on the properties of the surface and the angle at which the light ray strikes it.
If two trains are 2000 miles apart on the some track one travels east at a velocity of 150 mph the other travels west at a velocity of 100 mph how long will it take for them to meet?
The closing velocity is speed1 plus speed2, so the trains are moving toward each other at 250 mph. 2000/250 = 8. The trains will meet in 8 hours.
What is the participial phrase of the cattle grazing in the evening dusk headed toward the barn?
grazing in the evening dusk
An earthworm crawled 35millimeters directly toward a rock at a constant velocity. It took the earthworm 2.5seconds to crawl that far. What was the earthworm's velocity?
14 millimeters per second Explanation; The velocity of an object is the distance it travels divided by the time it takes to travel that distance. In this case, the earthworm crawled 35 millimeters in 2.5 seconds, so its velocity was ( 350/2.5) = 14 millimeters per second.
How when something travels in a circle its always accelerating?
When an object travels in a circle, it is constantly changing direction, which means its velocity is also changing, even if its speed remains constant. Acceleration is defined as the rate of change of velocity, and since velocity includes both speed and direction, any change in direction constitutes acceleration. This continuous change in direction toward the center of the circle is what is known as centripetal acceleration. Therefore, an object in circular motion is always accelerating due to this constant change in direction.
When will an object falling toward earth accelerating?
at terminal velocity
What direction does the angular velocity vector of the Earth's rotation point toward?
The Earth's angular velocity vector due to its axial rotation points towards the north pole.
When a light wave bends toward the normal what does that tell you about the velocity?
It decreases.
A land breeze usually originates during the?
evening and flows toward the water.

As blood travels from the aorta toward the capillaries the?
The resistance will increase
When gravitational forces and air resistance equalize on an object that is falling toward earth and the objects stop accelerating its velocity is called the?
terminal velocity
What can velocity be compared with?
'Velocity' should be compared with 'speed', and it should be understood that they're different. "30 miles per hour" is a speed. "30 miles per hour toward the south" is a velocity.
