Momentum = m V = 45 x 7.6 = 342 kg-m/sec
Using p=mv. p: momentum (kg ms^-1) m: mass (kg) v: velocity (ms^1) p = (25)(4) = 100 kg ms^-1
29.0576 meters per second.
Momentum = (mass) x (speed)But if mass is in kg, then speed should be in meters per second, otherwise we'll geta very strange unit for our momentum (kg-mile-sec-1).1 mile = 1,609.344 meters18 miles = 28,968.2 metersMomentum = (1,400) x (28,968.2) = 40,555,468.8 kg-meter per second=============================Doing a double-take on the question ... there's got to be a mistake there somewhere.The car is going " ... 18 miles per second ... ". That's roughly equivalent to the earth's meanorbital velocity around the sun, and equal to 64,800 miles per hour.18 miles per hour, or 18 meters per second, would be a lot more reasonable.But we're only here to answer the question as posted, whether it makes sense or not.
Take 200 divide by 20!
The answer is in the question. 40 m/s is how fast it is going. This means in one second, the object has traveled 40 meters. Relatively fast compared to walking or driving.
Momentum = (mass) times (velocity) = (50 + 30) (10) = 800 kilogram-meters per second.
Using p=mv. p: momentum (kg ms^-1) m: mass (kg) v: velocity (ms^1) p = (25)(4) = 100 kg ms^-1
33.33 meters per second.
6m/1.4s = 4.29M/S
The elephant would have more momentum because of it has a greater mass and is going faster. The direction really doesn't matter
69 meters per second
29.0576 meters per second.
900 meters/30 seconds = 30 meters/second
momentum and swimming are related because you need momentum to keep you going
A team that has the momentum is on the move and is going to take some effort to stop. A team that has a lot of momentum is really on the move and is going to be hard to stop. A sports team which is on the move has the momentum. If an object is in motion (on the move) then it has momentum.
At 40 centimeters per second, you are traveling 24 meters per minute.
