What type of energy is energy of motion which depends on the mass and velocity of an object?
Kinetic energy.
Specifically
K.E. = ½mv²
where
K.E. is kinetic energy
m is mass
v is velocity
You can not convert a distance to a speed.
To convert either km to miles, or km/hour to mph, divide the number by 1.6, approximately.

Object hanging on a tree a kinetic or potential energy?
Potential energy is the energy contained in the position of an object, so object hanging on a tree would be potential energy.
How to convert a velocity time graph into a position time graph?
The position at time t (and therefore the height of the p-t graph) will be the area under the v-t curve between time 0 and t.
What are the condition for an object to stay at rest to keep moving at constant velocity?
The condition for an object to stay at rest or if moving, moving at a constant
velocity is that the sum of forces acting on the object be zero or that no force
acts on the object.
What does a straight line slanting up from left to right on a distance versus time graph show?
It represents that the object is remaining at a fixed distance. Typically that means it is not moving.
Do states have a speed limit of 75 miles per hour on urban interstates?
75 mph is equal to 120.7 kilometers per hour
What animal is the fastest flyer 105 miles per hour?
The Spine-tailed Swift is the fastest flying bird. This Asian bird has been recorded at speeds up to 106 miles per hour. Note: Falcons have been clocked at higher speeds when diving from high altitudes but never in level flight.
How do you find the speed with mass and kinetic energy?
|v| = sqrt( 2 * KE / m ), with |v| being speed.
The knot is a unit of speed equal to one nautical mile per hour, approximately 1.151 mph. Thus, 429 knots is 429 x 1.151 = 493.779 mph
How does the kinetic energy of substance increase?
As the kinetic energy of matter is increased, the temperature increases and phase changes from solid to liquid or liquid to gas occur. If pressure is low enough, sublimation could occur.
What happens to the energy of a ball when it is dropped to the floor?
The kinetic energy of the ball is converted into elastic energy through deformation (I assume we are not talking about steel balls). The elastic energy is then released, pushing the ball back up. Some energy is lost in the ball where it will cause heating, and some is probably lost to the floor, depending how elastic the floor is, so the rebound bounce won't reach the same height as the initial height, but total energy must be conserved.
In kilometers per hour, 133MPH is approximately 214.04KMPH.
When bullet penetrates into the target what happens?
There is a Reaction, called recall or kick.
That should read "recoil."
How do you find deceleration when you do not know final velocity?
You must use what you DO know, along with an appropriate equation or formula
from the toolbox of formulas you've collected during your study of Physics.
Example:
If you know the total distance covered and the elapsed time,
then you can use the familiar formula ...
x = 1/2 A T2
but solve it for 'A' (acceleration):
2x = A T2
A = 2x/T2 .
What is the mathematical relationship between momentum and kinetic energy of the body?
Kinetic energy is the sum of all the parts of momentum:
p=mv >function for momentum
∫ p=∫ mv.dv >integrate both sides with respect to velocity
∫ p=.5mv²=Ek >results in formula for kinetic energy
How far can you run 9 miles per hour in 45 minutes?
At 9 miles per hour you can run 6.75 miles in 45 minutes.
The answer is: The momentum (mv) after the collision is the same as
the momentum before it. The rest is just arithmetic.
Before the collision, the momentum of the bullet is mv=(0.01)x(400) = 4 kg-m/sec.
After the collision, the combined mass of the wood block plus the bullet is 910 gm.
Its momentum mv=(0.910)x(v) = 4 kgm-m/sec.
v = 4/0.910 = 4.396 m/sec .
I've ignored the momentum lost during the embedding due to crunching and splintering,
both because I don't know anything about the properties of the wood, and also because
I wouldn't know what to do with them.
If you are going 35 mph how many feet will you travel in 10 seconds?
146.66 feet every 10 seconds at 10 mph.
What does the slope of the line on a position versus time graph tell you about the objects speed?
The distance versus time graph shows the position of the object. The slope of the line shows the velocity of the object. The velocity is the direction and speed of an object. If your slope has a positive slant that means you are going in a positive direction. If the slope has a negative slant your object is going in a negative direction. If your slope is zero (a horizontal line) that means your object has stopped and is about to change directions.
In case you didnt know a positive slant looks like this on a graph.... /
a negative slant looks like this on a graph.... \
postive is like sloping up a hill
negative is like falling down the hill
What is top speed for the 2005 yz250f?
the top speed on my 87 lt250r with no mods is 88 mph, although when that speed was reached the front end seem to shake and wobble violenty, I do not recommend doing tghis on the street as i did! I hope this helps, Oh yeh the reason i know is thatit costed me around 700.00 dollars for fleeing and illuding !!!
