Kinetic energy = (1/2) (mass) (velocity squared)
Divide each side
by (velocity squared/2): Mass in kg = ( 2 x energy in joules) / (velocity in m/s) 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.
The kinetic energy of the object moving with a velocity of 5 meter per second is 25 joules. What will be the kinetic energy when the velocity is tripled?
The object has a mass of 2kg. When velocity is tripled the kinetic energy becomes 225 joules.
How do you Calculate the mass of an object of 180 joules and rest at 15 meters from the ground?
How do you calculate the mass of an object that has a potential energy of 180 joules and rest at the top of a hill 15 meters from the ground?
How do you find force given velocity time and mass?
Not enough information. You can calculate force by Newton's Second Law, but in this case, there is no way to know how fast the velocity changes - or whether it changes at all.
What units are kinetic energy measured in?
To measure kinetic energy:Let us suppose an object of mass m moving wtih velocity vKinetic Energy of that object= mv2/2
How do you calculate force when mass and velocity are given?
Force equals the mass times the rate of change of the velocity.
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 mass if you given velocity?
That's not enough information. You need some additional information to calculate the mass.
How do you calculate power when given speed acceleration weight and distance?
Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.
How to find potential energy when only mass and velocity time is given?
To get the potential energy when only the mass and velocity time has been given, simply multiply mass and the velocity time given.

How do you find mass if you are given the momentum and the speed?
momentum = mass x velocity => mass = momentum / velocity
How can you find force when mass and velocity are given?
You cannot. Force = Mass*Acceleration or Mass*Rate of change of Velocity.
How do you find velocity when given the time and mass?
You can't. The mass is irrelevant to velocity. You need the distance.
What will be the kinetic energy and velocity of object of mass 62kg?
Its kinetic energy (in joules) will be (31) times (its velocity in meters per second)2 .
