1 2 of a number m?
m/2
What does m mean after a number?
In the metric system "m" is the abbreviation for metresmaking the number a measure of distance.
What is the quotient of a number and 10?
either m/10 or 10/m (/=divide)
What is twice the quotient of a number m and 35?
m divided by 70
How do you write a number that exceeds m by 4 in an algebraic expression?
m + 4
When mass and speed of a moving body are doubled what happens to its kinetic energy?
Momentum = (mass x velocity) = M V If velocity is doubled, then new momentum = (M x 2V) = 2 x (M V) = double the original momentum. ========================= Kinetic energy = 1/2 M V2 If 'V' is doubled, then new KE = (1/2 M) (2V)2 = (1/2 M) (4V2) = 4 (1/2 M V2) = 4 times original KE.
Derivative of kinetic energy?
Kinetic energy is a measure of energy and is therefore measured in joules (J). In S.I. units, a J can be written in its most basic form as: (kg m^2)/(s^2) This is apparent from the kinetic energy equation: KE = (1/2) m v^2
If a sprinter has a mass of 80 kg and a kinetic energy of 3000 what is the speed?
Although the units of the kinetic energy aren't given, we have to assume that the "3,000"are joules ... the SI unit of energy; otherwise we can't go anywhere at all with this question.K.E. = 1/2 m V2 = 3,000 joulesm V2 = 6,00080 V2 = 6,000V2 = 6,000/80 = 75V = sqrt(75) = 8.66 meters per second (rounded)
How do you find the mass when given speed and kinetic energy?
You solve the equation for kinetic energy for mass. KE = (1/2) m v2 (1/2) m v2 = KE m = 2 KE / v2
Does a floating feather have both kinetic and potential energy?
If the feather is moving, it has potential energy equal to half of the product of its mass (m) and the square of its velocity (v2), such that EK=(m*v2)/2 If the feather is in the air close to a body of large mass (e.g. Earth), it also has potential energy due to gravity equal to the product of its mass (m), the distance it has available to fall (h), and the local acceleration due to gravity (g), such that EP,G=m*g*h
If the mass of a ball is161gmoving at a speed of 39ms to the power of -1calculate the kinetic energy?
Ek = 1/2 * m * v^2 Ek = 1/2 * 161 g * (39 m/s)^2 Ek = 1/2 * 161g * (1kg / 1000g) * (39 m/s)^2 Ek = 254 kgm^2/s^2 Ek = 254 J
Which of these objects has the most mechanical kinetic energy a spring compressed a rock sitting on a cliff a bycicle going 10mph a car going 60 mph?
Kinetic energy is energy available due to velocity, so you can exclude the compressed spring and the rock sitting on a cliff. As far as the bicycle vs the car, the car is the easy winner. EK = 0.5 m v2 Since both the mass (m) and the velocity (v) of the car exceeds that of the bicycle, it is clear that EK-Car is much greater than EK-Bicycle.
A 100g steel ball falls from a height of 1.80m on to a horizontal plate and rebounds to a height of 1.25m. Find its Ek as it leaves the plate on the rebound and its velocity of rebound?
The ball at a height has a certain potential energy and the potential energy in relation to plate at the highest point after rebound will be equal to ball's total kinetic energy an instant after rebound. The first figure of 1.80 m isn't necessary to perform calculations.Ep = m * g * hEk = m * v2 / 2Ek = Ep = 0.1 * 9.81 * 1.25 = 1.22625 Jv = sqrt(2 * Ek / m) = 4.9523 m/s

Can use 9600 gt in asusM4N68T-M LE V2?
Yeah
What speed must a particle move for its mass to double?
M = M0 / sqrt( 1 - v2/c2 )If M = 2M0 thensqrt( 1 - v2/c2 ) = 0.5( 1 - v2/c2 ) = 0.251 - 0.25 = 0.75 = v2/c2v2 = 0.75 c2v = sqrt(0.75) c = 0.866 c = 259,627,885 meters (161,325 miles) per second
What is the kinetic energy of an object with a mass of 18 kg moving at 25 ms?
The formula for kinetic energy is KE = 1/2 x m x v2 where m is the mass measured in kg and v is the velocity measured in m/s. We are given that m = 500.0 kg and that v = 35.0 m/s. Thus, KE = 1/2 x 500.0 kg x (35.0 m/s)2 = 306250 J or 3.06 x 105 J if you are using significant figures. (Note that 1 J = 1 kg m2/s2.)
