A 3kw engine operates for 3secs, 10kgf force is applied find the Displacement.

To find the displacement, we need to know the acceleration experienced by the object. However, in the given question, we are only given the power of the engine and the time for which it operates, as well as the force applied. With this information, we cannot directly calculate the displacement.

The power of an engine is given by the formula:

Power = Force * Velocity

Where Power is measured in watts (W), Force in newtons (N), and Velocity in meters per second (m/s). In this case, the power is given as 3 kW (kilowatts). We need to convert this to watts by multiplying it by 1000:

Power = 3000 W

Unfortunately, the given force of 10 kgf (kilogram-force) cannot be directly used in the equation since it is a unit of force and not of mass. We need to convert it to newtons.

The conversion factor between kgf and N is approximately 9.81 N/kgf. So, the force in newtons can be calculated as:

Force (N) = 10 kgf * 9.81 N/kgf

Once we have the force in newtons, we need to determine the velocity by dividing the power by the force:

Velocity (m/s) = Power (W) / Force (N)

Finally, to find the displacement, we multiply the velocity by the time the engine operates:

Displacement (m) = Velocity (m/s) * Time (s)

Please provide the value of time for further calculations.
