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.

What is 75kg in joules?
Mass is measured in kilograms, not in joules. Joules are a unit of energy. To calculate the energy of a 75kg mass, you would need additional information such as the velocity or height it is at.
How many joule is 300 fps?
To convert feet per second (fps) to joules, you need the mass of the projectile. The formula to calculate joules is 0.5 * mass * velocity^2. Without knowing the mass of the projectile, it is not possible to accurately calculate joules based solely on the velocity of 300 fps.
Mass is 145g and velocity is 25ms Find the answer using kinetic energy formula?
The formula for kinetic energy is KE = 0.5 * mass * velocity^2. Plugging the values given (mass = 145g = 0.145kg, velocity = 25 m/s) into the formula, we get KE = 0.5 * 0.145 * 25^2 = 45.31 Joules.
How can calculate recoil velocity of gun?
The recoil velocity of a gun can be calculated using the principle of conservation of momentum. The formula to calculate the recoil velocity is: Recoil velocity = (mass of bullet * velocity of bullet) / mass of gun. This formula takes into account the mass of the bullet, the velocity of the bullet, and the mass of the gun.
How do you find force given velocity time and mass?
You can find force using Newton's second law, which states that force is equal to mass times acceleration. Since acceleration is the rate of change of velocity over time, you can calculate acceleration from the given velocity and time. Then, multiply the mass by the acceleration to find the force.
How many joule is 300 fps?
To convert feet per second (fps) to joules, you need the mass of the projectile. The formula to calculate joules is 0.5 * mass * velocity^2. Without knowing the mass of the projectile, it is not possible to accurately calculate joules based solely on the velocity of 300 fps.
What is 75kg in joules?
Mass is measured in kilograms, not in joules. Joules are a unit of energy. To calculate the energy of a 75kg mass, you would need additional information such as the velocity or height it is at.
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.
Mass is 145g and velocity is 25ms Find the answer using kinetic energy formula?
The formula for kinetic energy is KE = 0.5 * mass * velocity^2. Plugging the values given (mass = 145g = 0.145kg, velocity = 25 m/s) into the formula, we get KE = 0.5 * 0.145 * 25^2 = 45.31 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 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 force given velocity time and mass?
You can find force using Newton's second law, which states that force is equal to mass times acceleration. Since acceleration is the rate of change of velocity over time, you can calculate acceleration from the given velocity and time. Then, multiply the mass by the acceleration to find the force.
A bomb of 12kg explodes in two pieces of masses 4kg and 8kg The velocity of 8kg mass is 6msecThe kinetic energy of the other mass is?
To find the kinetic energy of the 4kg mass, we first calculate the velocity of the 4kg mass by using the principle of conservation of momentum. The total momentum before the explosion is equal to the total momentum after the explosion. Once we have the velocity of the 4kg mass, we can then calculate its kinetic energy using the formula KE = 0.5 * mass * velocity^2.
How do you find velocity with charge and joule?
To find velocity with charge and joules, you would need additional information such as the mass of the object or particle carrying the charge. Once you have the mass, you can use the formula for kinetic energy, which incorporates velocity, charge, and energy (in joules) as factors to solve for velocity.
How do you find mass if you are given the momentum and the speed?
momentum = mass x velocity => mass = momentum / velocity
