To calculate the power dissipated in a mechanical system, you need to know the force and velocity involved.

Power dissipation is the rate at which energy is lost in a system due to friction, air resistance, or other factors. It is measured in watts (W) and can be calculated using the formula P = Fv, where P is power, F is force, and v is velocity.

To calculate the force, you need to know the mass of the object and the acceleration it experiences. Force is measured in newtons (N) and can be calculated using the formula F = ma, where m is mass and a is acceleration.

To calculate the velocity, you need to know the distance travelled and the time taken. Velocity is measured in metres per second (m/s) and can be calculated using the formula v = d/t, where d is distance and t is time.

Once you have calculated the force and velocity, you can use the formula P = Fv to find the power dissipated in the system.

It is important to note that power dissipation is not the same as power output. Power output is the rate at which energy is transferred to the system, while power dissipation is the rate at which energy is lost from the system.
