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.
Converting kilograms to Joules?
To convert kilograms to joules, you need to use Einstein's famous equation E=mc^2, where E is the energy in joules, m is the mass in kilograms, and c is the speed of light (approximately 3 x 10^8 m/s). Simply multiply the mass in kilograms by the speed of light squared to find the energy in joules.
If momentum and mass is given how to find speed?
You can find the speed by dividing the momentum by the mass. The formula to calculate speed is speed = momentum / mass. Just plug in the values for momentum and mass, and you will get the speed.
How do you find mass if you are given the momentum and the speed?
momentum = mass x velocity => mass = momentum / velocity
How do you calculate mass when given joules and velocity?
To calculate mass when given joules and velocity, you can use the formula for kinetic energy: KE = 0.5 * m * v^2, where KE is the energy in joules, m is the mass, and v is the velocity. Rearrange the formula to solve for mass: m = 2 * KE / v^2. Plug in the values for energy and velocity to find the mass.
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)
How do you find a mass of a substance dissolved in a solution given temperature and joules?
You can use the formula q = mcΔT, where q is the heat energy transferred, m is the mass of the substance, c is the specific heat capacity, and ΔT is the temperature change. Rearrange the formula to solve for mass (m) by dividing both sides by cΔT. Given the specific heat capacity of the solute, you can calculate the mass of the substance dissolved in the solution by plugging in the given values for temperature and heat energy.
What is the kinetic energy of a 1 kg mass that is moving with a speed of 20 ms?
The kinetic energy of a moving object is given by the formula 1/2 * mass * speed^2. Plugging in the values for the mass (1 kg) and speed (20 m/s), the kinetic energy would be 200 J.
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 is the kinetic energy (in J) of an N2 molecule moving at this speed?
The kinetic energy of a molecule is given by the formula KE = 0.5 * m * v^2, where m is the mass of the molecule and v is its velocity. For an N2 molecule moving at a certain speed, you would need to know the speed and the mass of the molecule to calculate the kinetic energy in joules.
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
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
