You solve the equation for kinetic energy for mass.
KE = (1/2) m v2
(1/2) m v2 = KE
m = 2 KE / v2

How do you find the speed given joules and mass?
Use the formula for Kinetic Energy (KE), which is the energy due to the motion of an object. KE = (1/2) * (mass) * (velocity)2 where KE is in joules, mass is in kg, and velocity (or speed) would be in meters/sec...Just substitute the appropriate numbers, rearrange and solve for velocity
How do you find work given mass initial velocity and final velocity?
We assume you mean the work done in order to change the velocity of the moving mass.Easiest way is to calculate the change in the kinetic energy of the moving mass, and realizethat it's equal to the amount of work either put into the motion of the mass or taken out of it.Initial kinetic energy = 1/2 m Vi2Final kinetic energy = 1/2 m Vf2Change in kinetic energy = 1/2 m ( Vf2 - Vi2)
How do you find distance given acceleration and speed?
acceleration times speed
How do you find the speed of an object given distance and time?
Divide the distance by the time; the quotient is speed.
How do you find speed if average speed is given?
It is a bit hard to answer your question, as it lacked of a few things: Total Distance or total time, the distance which the speed(answer) is in or the amount of time the person travels with the speed(answer).
How do you find mean kinetic energy when given only mass and horizontal distance traveled?
You don't have enough information in this case. Kinetic energy depends on mass and speed. Speed can be calculated as distance / time - and no time is given, nor is there any other information that allows you to calculate the time. Note that even if time is given, you can calculate the average (mean) speed, but that will only give you a rough idea of the mean kinetic energy. In this problem, if the speed changes a lot, the average kinetic energy (averaged over time) will be greater than in the case of a constant speed. This is because kinetic energy is proportional to the square of the speed.
How do you find kinetic energy if no final velocity is given?
Kinetic energy is equal to potential energy during the change
A change in a objects speed has a what effect on its kinetic energy than a change in mass?
Doubling the speed. This is because the (non-relativistic) kinetic energy is proportional to the square of the speed.
How do you find the speed with mass and kinetic energy?
|v| = sqrt( 2 * KE / m ), with |v| being speed.
What makes an object have more kinetic energy?
An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly. An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly.
How do you find speed in Kinetic Energy?
1/2 times mass times velocity2 :)
How do you calculate kinetic energy with mass and velocity?
Kinetic energy = 1/2 (mass) (speed)2 2 x kinetic energy/mass = (speed)2 Speed = square root of ( 2 x kinetic energy/mass )
Suppose you pedal a 25kg bicycle at 1.5 m. Find the kinetic energy of bicycle?
Kinetic Energy is given by: 1/2MV2 . So, substituting values: (1/2)*(25)*(1.5)^2 = 28.125J
Where do you find kinetic energy?
kinetic energy is the energy possessed by a body by virtue of its motion. So you can find kinetic energy in a car,in a ball falling due to the earth's pull,yourself while walking etc
How do you find the kinetic energy of a gas when given molecules and temperature?
The relation between temperature and energy is given by the Boltzmann equation. Boltzmann found a consatn( called the boltzmann constant) that relates the two. That is Energy=k*T
How do you find the ratio of kinetic energy?
The answer depends on what two (or more) things the ratio is meant to compare. The kinetic energy of several objects? The kinetic energy of an object compared to its total energy? The kinetic energy compared to its engine size?
How do you find the speed given joules and mass?
