The mass will be equal to the kinetic energy divided by the velocity squared.

m=2(KE)/(v2). This is from the basic equation KE=1/2mv2.

Use the formula KE = (1/2) mv2. (Kinetic energy = 1/2 x mass x speed squared.) Replace the values you know, and solve the resulting equation for the speed.

The formula for kinetic energy is: KE = (1/2)mv2. Just solve this equation for mass. (To isolate the mass, multiply both sides of the equation by 2, divide both sides of the equation by v2).

You can't. You also have to know the mass, or have a way to find it.

How cn you calculate kinetic energy?

Kinetic Energy = 1/2 Mass * Velocity squared


How do you solve the time by the given of mass and kinetic energy?

Kinetic energy is equal to one-half of the product of an object's mass and the square of its velocity. Velocity is change in displacement divided by time. If you have the kinetic energy and mass, you can calculate the velocity by taking the square root of the quotient of kinetic energy and mass, and thereby solving for the velocity.


How do you calculate velocity using kinetic energy?

KE= 0.5mv2 so we have KE=50 m=50 v=1.414m/s


When you have kinetic energy you must have?

When you have kinetic energy, you must have a mass and a velocity since kinetic energy is half the product of the mass and the square of the velocity.


What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?

Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4


Why do you need momentum with kinetic energy?

Momentum is the product of mass and velocity. Kinetic Energy is the product of mass and velocity squared. As you can see, since Kinetic Energy is derived from mass and velocity, and Momentum is derived from mass and velocity, you cannot have one without the other.


Does kinetic energy increase with speed and time?

Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.


Do changes in velocity and mass have the same effect on kinetic energy?

Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.


How do weight and kinetic energy relate?

Ofcourse, actually, you have to have mass in order to calculate kinetic energy. Kinetic Energy = 0.5*m*v^2 Where m is the mass. Where v is the velocity. Mass is directly proportional to the kinetic energy, the more the mass, the more the kinetic energy.


What two factors determine an object kinetic energy?

Kinetic energy is given by the following equaiton: KE = 0.5*m*v^2 Where KE is kinetic energy, m is the object's mass, and v is its velocity. In other words, an object's kinetic energy is dependent on its mass and the square of its velocity. Note that since the velocity term is squared, velocity has a larger effect on kinetic energy than mass. For example, if you double mass, the kinetic energy will also double, but if you double velocity, kinetic energy increases by a factor of four.

How do you calculate mass when given joules and velocity?

Kinetic energy = (1/2) (mass) (velocity squared)Divide each sideby (velocity squared/2): Mass in kg = ( 2 x energy in joules) / (velocity in m/s) squared
