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.
V=FxW. Work it out yourself? Pretty sure google can do that calculation. It's really quite obvious when you think that you want the answer in mm/s.... First off you know the wave travels 0.11mm 2000 times every second. So it travels at 2000*0.11mm/s. The answer would be needed in m/s normally so convert 0.11mm into meters first.
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".
(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
5 m/s south
If April swam 50 M North then swam 20 M South back then her velocity would be 16.66. This is a math problem.

2000 seconds is equivalent to 33 minutes and 20 seconds. To break it down, there are 60 seconds in a minute, so 2000 divided by 60 gives you approximately 33 minutes, with a remainder of 20 seconds.
2000
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.

To find the speed, first convert 7 minutes and 35 seconds to seconds only (455 seconds total). Then, divide the distance (2000 meters) by the time (455 seconds) to get the speed: 2000 meters / 455 seconds = 4.40 meters per second.
2,000 hours is 7,200,000 seconds.
