Velocity is distance/time. So, 2000/400 reduces to 5 m/s, but since velocity is a vector, direction MUST be stated along with the speed we just calculated. The final answer is 5 m/s South (or 270 degrees).
Just use the definition of momentum, as mass x velocity. In this case, you need to divide the momentum by the mass, to get the velocity.
(Momentum) = (mass) x (velocity) If you know the momentum and the mass, you can find the velocity. Do you know how to do algebra? (velocity) = (Momentum) / (mass) = (30,000 kg m/s) / (400 kg) = 75 m/s
It will be 8000 joules. ( if the velocity of a car has been doubled, the KE will be quadrupled. Because the KE is directly proportional to the velocity squared.)KE= 1/2 m v2
Velocity is a quantity that has magnitude and direction. The magnitude of velocity is what we call "speed".If the velocity is constant, then its magnitude and direction are both constant.Constant magnitude means constant speed.So the answer to the question is "Yes".
Terminal velocity is when air resistance balances out with gravity. For humans it's usually around 2000 ft of falling, gravity accelerates the person towards the ground at about 9.8m/s, as said person speeds up, air resistance increases and it becomes harder to accelerate. Terminal velocity is the point at which one may no longer accelerate. To control it: more air resistance = slower descent (terminal velocity comes sooner and is not as fast (i.e.parachutes), less air resistance = faster descent, it may take longer to reach terminal velocity as it is a much higher speed.
5 m/s south
Ed biked home from school in 400 seconds. His home is located 2000 m south of the school. What was his velocity
There are: 2000/60 = 33 minutes and 20 seconds in 2000 seconds, since there are 60 seconds in a minute.there are 60 sec/min so take 2000 seconds and divide by (60 sec/min) to get 33.333 minutes.
When Seconds Count - 2000 TV was released on: USA: 24 May 2000
2,000 hours is 7,200,000 seconds.
Seconds Before the Accident was created in 2000.
Every Six Seconds was created in 2000.
There are about 0.5556 hours in 2000 seconds. That is also about 33.33 minutes, or exactly 33 minutes and 20 seconds.
