An object moving at 30 miles per ssecond takes 5 s to come to a stop what is the object's acceleration?
The object's acceleration is equal to the change in velocity divided by the time taken. The initial velocity is 30 miles per second, and the final velocity is 0 miles per second. The change in velocity is 30 miles per second. Therefore, the acceleration is 30 miles per second divided by 5 seconds, which is 6 miles per second squared.
What is an example of Newtons 2 law?
Think of it like this-- what would hurt more: getting hit by a go kart at 10 miles per hour or a Mack Truck at 100 mph? The 2nd would hurt more because there is a lot more Force (more mass in the truck and more acceleration from the impact. Though the vehicles in my example are not accelerating your body would be because it would be going from zero to 10, or 100 mph instantly)
What is the escape velocity of planet Jupiter in miles per hour?
The escape velocity of planet Jupiter is: ~133,097.71 miles per hour.
What is time velocity?
Meaningless question, I'm afraid! Velocity is speed in a given direction. Speed is the distance travelled per unit time (eg miles per hour). "Time velocity" would therefore mean a distance in given direction, though why you'd want to describe it like this I have no idea, unless it was to try and baffle with pseudo-science!
The velocity of visible light wave is?
The velocity of visible light in a vacuum is approximately 299,792 kilometers per second, which is also equal to 186,282 miles per second. It varies slightly when passing through different mediums such as air, water, or glass due to changes in its wavelength and frequency.
What is the effect on the force if the velocity changes from 5 miles per hour to 10 miles per hour?
Itis an accelerating force but without a measure of the time over which the speed velocity changed, it is not possible to say more.
If velocity dSdt and speed dSdt then what happened when a body move in a complete circle were dS0 then velocity?
Velocity is a vector, meaning it has a direction, like east, north, up. Speed isa magnitude without direction, 60 miles per hour is a speed; 60 miles per hour north is a velocity. When a care is going 60 mph in a circle the speed is constant but the velocity changes as the direction changes. The magnitude of the velocity is the same but the direction changes thus the velocity changes. Velocity changes if either the speed/magnitude or the direction change.
What is the terminal velocity of cats?
The terminal velocity of a cat is around 60 miles per hour, which is the speed at which they reach maximum falling velocity due to air resistance balancing out the force of gravity.
What is the maximum velocity of a falling person?
The maximum velocity of a falling person in free fall is terminal velocity, which is about 120 mph (200 km/h). This occurs when the force of air resistance equals the force of gravity, resulting in a constant velocity.
Do both cars have the same velocity if they are going in different directions at seventy miles per hour?
No, they don't. Velocity is a vector - made up of both a magnitude (number), and a direction. If any of the two changes, the velocity is not the same. If you are interested only in the magnitude, you talk about "speed", not "velocity".
What is the force of an object 435 grains in weight at 86 miles per hour?
If an object of 435 grains is moving at a constant velocity of 86 miles per hour, its acceleration is zero. Since F=ma and a=0, the force on the object is zero.
What is the SI units for timevelocityworkspeedforce?
Time is universally measured in seconds. Velocity can be measured to whatever is practical, whether it be miles per hour or metres per second. Velocity also has a direction in the label. Work is the measure of the amount of energy transferred by a force. Measured in joules. Speed is the same as velocity, minus the direction. Force is measured in Newtons.
How fast can a man fall to earth from airplane?
The fastest rate a human can fall is called terminal velocity. Terminal velocity is when the gravity force upon an object is equal to that of the wind resistance. The normal terminal velocity of a human is around 125 miles per hour.
How can object accelerate when it does not change speed?
Let's review some terms before we tackle this one. Speed is displacement per unit of time. We know 60 miles per hour is a speed. Velocity is speed with a direction vector associated with it. We know 60 miles per hour east is velocity. Acceleration is a change in velocity. That means if an object changes its speed or its direction or both, it is accelerating.If an object has a given velocity and it slows down or speeds up, it is accelerated. But if the same object changes direction without a change in speed, it is still experiencing acceleration. A force had to act on the object to change its direction, even though its speed didn't change. Thus, an object can accelerate even though it does not change speed.
What is the velocity of a tsunami with a wavelength of 125 miles and a period of 15 minutes?
velocity=500 miles per hour
Is there a simple way of calculating how fast a satellite needs to move in order to orbit a body at a specific distance?
Yes. The orbit occurs at apparent "zero G" when the gravity force inward equals the centripetal force pulling it outward. The gravity force is F = mass times gravity acceleration and the centripetal force is mass times velocity squared over radius. velocity = square root (radius time gravity acceleration) Using earth radius of 4000 miles plus orbit altitude of say 300 miles and gravity at 32 feet per second per second gives a velocity of about 17,500 miles per hour
Is the force of gravity the same on an object fifty miles above the earth?
Yes. Gravity is a constant force. It never changes as long as you are within it's pull.
