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.
