momentum = mass x velocity => mass = momentum / velocity
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.
You can't. The mass is irrelevant to velocity. You need the distance.
You cannot. Force = Mass*Acceleration or Mass*Rate of change of Velocity.
You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.

To get the potential energy when only the mass and velocity time has been given, simply multiply mass and the velocity time given.

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
To find the velocity, you can use the formula for momentum: momentum = mass x velocity. Rearranging the formula to solve for velocity, you get velocity = momentum / mass. Plugging in the values given, velocity = 22 kg m/s / 7.3 kg ≈ 3 m/s.
The two factors that determine how much kinetic energy something has are its mass and its velocity. The kinetic energy of an object is directly proportional to both its mass and the square of its velocity.
You can find the mass by dividing the momentum by the velocity. The formula for momentum is mass multiplied by velocity, so by rearranging the formula you can solve for mass by dividing momentum by velocity.
