What is the momentum of a 1500 pound car traveling at 5 mph?
Momentum = (mass) x (speed) = 7,500 poundmass-miles per hourAfter laboriously converting all of that to metric units for you ... at noextra cost ... we find that the momentum is equivalent to1,520.8 kilogram-meters/second
If you roll two different but identical balls off of a table at the same time and one is moving 1 meters per second and the other is moving 5 meters per second which one will hit the ground first?
First, we have to do some mental gymnastics and decide what the question means by "different but identical".Let's assume it's talking about two copies of the same item, like two separate identical twins.What the question seems to be describing is the situation where both balls are rolling horizontallyacross the table toward the edge. One is rolling much faster than the other, but they both reach theedge and fall off at the same instant.They will hit the floor at the same instant. The one that was rolling faster before the fall will hit thefloor farther from the foot of the table, but the two "clunks" as they hit will come at the same instant.
What is 4 meters x 4 meters in square meters?
16 meters squared
What is the number between 8 meters and 9 meters?
8.5 meters or 8 1/2 meters
How many square meters is 7 meters by 4 meters?
7 x 4 = 28 square meters.
What is the kinetic energy of a small 20 kilogram canoe is floating downriver at a speed of 2 meters per second?
40 Joules
What measures the kinetic energy?
Joules are the SI unit for energy. One Joule is equal to one kilogram meters squared per seconds squared (kgm2/s2).
What is the kinetic energy of a 200kg boulder when it is 1000m above the ground?
Kinetic energy = 1/2 (mass) (speed)2 = 1/2 (0.2) (200)2 = 4,000 joules
What is the kenetic energy of a 3-kilogram ball that is rolling at 2 meters per second?
Kinetic energy = (1/2)mv2, where m is mass and v is velocity.In this case, mass is 4 kg and velocity is 5 m/s, so K = (1/2)(4)(5)2 = 50 Joules.(The units of energy are Joules, as long as everything is measured in kilograms, meters, and seconds.)
A 5kg object is being lifted to a height of 8 meters and is dropped what is the kinetic energy of the object at 2 m?
After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy.

How fast would a 2-kilogram object need to move to have the same kinetic energy as a 4-kilogram object moving at 8 meters per second?
a.11.3 b.12.6 c.13.1 d.14.0
Why does kinetic energy depend on mass and speed?
Since kintetic energy is the energy of motion it depends on the two. mass affects inertia and inertia applies to kinetic energy. and speed is applied because the faster it going the more kinetic energy the object has.
What is the mathmetical formula for kinetic energy?
Kinetic Energy = 1/2(mass in kilograms)(meters per second)2
What is the kinetic energy of a 24 kilogram mass that is moving with a velocity of 2 meters per second?
KE = 1/2 m V2 = (12) (2)2 = 48 joules
What is the energy of a system by virtue of its motion?
That's called kinetic energy. The formula is: Kinetic energy = (1/2) x mass x velocity2. If mass is in kilograms, and velocity (or speed, really) in meters per second, the energy will be in Joules.
Is touching a kinetic energy?
Kinetic energy is the energy of motion. Your touching finger has mass and is moving some meters per second, so that motion is kenetic energy.
What are the factors in kinetic energy?
Kinetic energy = 1/2 x mass x velocity2. Mass in Kg, velocity in meters/sec, energy in Joules
