What is the value of work done on an object when a 50-newton force moves it 15 meters in the same direction as the force?

A. 435 joules
B. 97.3 joules
C. 750 joules
D. 693 joules

Answer :

Answer:

Work done, W = 750 joules

Explanation:

It is given that,

Force acting on the object, F = 50 N

It moves to a distance of, d = 15 meters

We need to find the work done on an object. We know that the product of force and distance covered is called the work done. As the force and the displacement are in same direction. So,

[tex]W=F\times d[/tex]

[tex]W=50\ N\times 15\ m[/tex]

W = 750 joules

So, the work done on an object is 750 joules. Hence, this is the required solution.

Final answer:

The work done on the object is 750 joules, calculated by the formula work equals force times distance, using the given values of a 50-newton force and a 15-meter distance.

Explanation:

The work done on an object can be calculated by using the formula W = F × d × cos(θ), where W is the work done, F is the force applied, d is the distance over which the force is applied, and θ is the angle between the force and the direction of motion. Since the force and the direction of motion are the same in this case, θ = 0 degrees and cos(0) = 1, thus the equation simplifies to W = F × d. The force exerted is 50 newtons, and the distance is 15 meters, so the work done on the object is W = (50 N) × (15 m) = 750 joules.
