To calculate the work done in pushing the weight up the inclined plane, you can use the formula:
Work = Force × Distance
The force exerted to push the weight up the inclined plane can be broken down into two components: the force parallel to the incline (F_parallel) and the force perpendicular to the incline (F_perpendicular).
The force parallel to the incline can be calculated using the formula: F_parallel = mg sin(θ), where m is the mass (4 kg), g is the acceleration due to gravity (9.8 m/s^2), and θ is the angle of inclination (π/4 radians).
The distance moved along the incline is the hypotenuse of the right triangle formed by the incline, which is given as 5 meters.
Now, calculate F_parallel: F_parallel = (4 kg) × (9.8 m/s^2) × sin(π/4 radians)
Then, calculate the work done: Work = F_parallel × Distance
Finally, substitute the values and compute the work.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
