A 250 g ball travels at a velocity of 40 m/s. Its momentum = mv where m is mass in kg and v is velocity in m/s
mv = 250/1000 x 40
10 kg m/s

A 250 gram ball travels at a velocity of 40 ms. It momentum is?
Momentum = (mass) times (velocity) = 0.25 x 40 = 10 kg-m/sec
Which has more momentum a 250 kg dolphin swimming at 6 meters per second or a 450 kg manatee swimming at 2 meters per second?
momentum = mass * velocity dolphin: 50kg*10.4m/s = 520 kg (m/s) elephant: 6300 kg * .11 m/s = 693 kg (m/s) The elephant has more momentum because of its large mass, and will be harder to stop/ change its course.
A ball starts at rest accelerates uniformly and travels 250m in 5 seconds What is the final velocity and the acceleration of the ball?
Average speed = (250 / 5) = 50 meters per second.Initial speed = 0Final speed = 100 m/sAcceleration = (100 / 5) = 20 m/s2===> Must be a rocket-propelled ball; its acceleration is 2G !
Which of the following has greater momentum a 500 kg car moving at 64 km a 250 kg cart moving at 12 km or a 1000 kg truck moving at 32 km?
Momentum (p) equals mass times velocity, or p=mv, and I assume that when the question says "moving at 64 km" it is referring to the cars velocity. The car will have a momentum of 32000 kg*km/s. The cart will have a momentum of 3000 kg*km/s. The truck will have a momentum of 32000 kg*km/s. The car and the truck both have a greater momentum than the cart.
What is the momentum of a 25kg sheep traveling east at 10ms?
The sheep's momentum vector has a magnitude of 250 kilogram-meters per second,and a direction of east.
A 250 gram ball travels at a velocity of 40 ms. It momentum is?
Momentum = (mass) times (velocity) = 0.25 x 40 = 10 kg-m/sec
If a plane moving at 250 ms and has a mass of 1000kg what is its momentum?
momentum is the product of the velocity and mass: 250,000 kg m/s
A net force of 200N acts on a 250kg object for 3 seconds What is the change in momentum?
F = ma so acceleration (a) = 200/250 ; the velocity after 3 second is v = at = 200/250 x 3 = 600/250 = 2.4 m/s; momentum change is mv = 250 x 2.4 = 600 kgm/s
Which has more momentum a 250 kg dolphin swimming at 6 meters per second or a 450 kg manatee swimming at 2 meters per second?
momentum = mass * velocity dolphin: 50kg*10.4m/s = 520 kg (m/s) elephant: 6300 kg * .11 m/s = 693 kg (m/s) The elephant has more momentum because of its large mass, and will be harder to stop/ change its course.
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.

Which has more momentum a 250 kilogram dolphin swimming at 4 miles per second or a 350 kilogram manatee swimming at 2 meters per second?
I think you mean the dolphin's velocity is 4 metres per second.In which case the dolphin's momentum will be 1000 kg.m/secThe manatee will have less momentum (700 kg.m/sec)Linear momentum = mass times velocity.By the way, 4 miles per second = 14,400 miles per hour.
What is the momentum of a 25kg sheep traveling east at 10ms?
The sheep's momentum vector has a magnitude of 250 kilogram-meters per second,and a direction of east.
Is it possible for a ball to have more momentum than a truck?
Momentum is mass times velocity. A bullet could theoretically have the same momentum as a moving truck if the bullet's speed is great enough. But practically, no--a bullet going that fast in the atmosphere would break up or burn up instantly. In outer space, it would be possible, but it would be hard to get the bullet up to that speed. Bullets already travel very fast (a fast bullet can go 4,000 feet per second, which is 2,700 miles per hour), but they are very light (a 250 grain bullet = 0.036 pounds). If a truck weighs 10 tons and is going 55 miles per hour, for instance, that 250 grain bullet would have to travel 30 million miles per hour to have the same momentum. Of course, the trivial answer is yes--both can have zero momentum if neither is moving!
What is the speed of a car that travels 250 km in 5 hours?
250 km in 5 hours = 250/5 = 50 km per hour.
How fast does sound travel through land?
