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 are given the momentum and the speed?
momentum = mass x velocity => mass = momentum / velocity
How can you find force when given distance and speed?
You cannot. Force is mass times acceleration. You have neither.
How do you find velocity given only mass and speed?
You can't, because you don't have enough information. In order to find velocity, you need to be able to find the speed and the direction of motion. You have the speed, but you have no information that you can use to determine the direction in which the object is moving. Mass doesn't help.
How do you find work if only mass and displacement is given?
First Find the Force Acting on Body take a = 9.8m/s F=ma Second Work Done = Force x Displacement Answer will be in Joules
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 do you find a mass of a substance dissolved in a solution given temperature and joules?
You can find the mass of a substance dissolved in a solution given temperature and joules using the relation q=mc(change in T). Where q is heat in joules, m is the mass, c is the specific heat capacity, and T is the temperature.
Converting kilograms to Joules?
Kilograms are mass units, Joules are energy units. You could use Einstein's energy-mass equivalence and multiply the mass (in kg) by the speed of light (in m/s) squared; that would give you the energy equivalent in Joules of a given mass.
If momentum and mass is given how to find speed?
Momentum = mass x speed so speed = momentum/mass or V=P/m
How do you find mass if you are given the momentum and the speed?
momentum = mass x velocity => mass = momentum / velocity
How get the solution of mass and speed of light?
Energy (in Joules) equals the mass (in Kgs) multiplied by the square of speed of light (in meters per second)
A girl on a motorbike passes by at a speed of 15 msec Her mass is 55kg What is her kinetic energy?
The kinetic energy of a 55 kg girl moving at a speed of 15m/s is?æ 6187.5 Joules. It is given by the formula 0.5mv^2 , where m is the mass of the body and v is its velocity.
How can you find force when given distance and speed?
You cannot. Force is mass times acceleration. You have neither.
How do you find velocity given only mass and speed?
You can't, because you don't have enough information. In order to find velocity, you need to be able to find the speed and the direction of motion. You have the speed, but you have no information that you can use to determine the direction in which the object is moving. Mass doesn't help.
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
What is a kinetic energy of an object that has mass of 20 kilograms and speed of 2.8ms?
78.4 joules at 2.8m/s
What is an object's kinetic energy if air resistance is not a factor and weighs 0.6 kg and its potential energy is 27 joules?
The object's kinetic energy can't be determined from the given information. Kinetic energy = (1/2) (mass) (speed)2 The question gives the object's mass, but we need its speed too.
How do you compare kinetic energies on things that move?
Kinetic energy = (1/2)*mass*(speed)^2 where, in metric units, mass is in kilograms, speed is in meters/second, and kinetic energy is in Joules. So, you need to know the mass and the speed of the things.
