Physics

To calculate the time, it takes for the motor to lift the load, we can break the problem down into several steps:

 

Calculate the force required to lift the load

The force required to lift the load is equal to the gravitational force acting on the load, which is given by:

Where:

is the mass of the load,

is the acceleration due to gravity.

 

Now, calculate the force:

 

Calculate the work done by the motor

The work done by the motor to lift the load is equal to the change in gravitational potential energy, which is:

Where:

is the force required to lift the load,
