calculate the work done when a 15N FORCE Push es a car 3m
please give me the step in how to work the problem
There is really only one step.
Work into the system by a force = force exerted times distance moved in the direction of the force.
15 N * 3 m = 45 Joules
To calculate the work done when a 15N force pushes a car for a distance of 3m, you can use the formula:
Work = Force × Distance × cos(θ)
Where:
- Work is the amount of work done (measured in joules, J)
- Force is the applied force (measured in newtons, N)
- Distance is the distance over which the force is applied (measured in meters, m)
- θ is the angle between the force and the direction of motion (in this case, we will assume it to be 0° since the force is directly pushing the car forward)
Now, let's calculate the work step-by-step:
Step 1: Assign the given values:
- Force (F) = 15N
- Distance (d) = 3m
- Angle (θ) = 0°
Step 2: Plug the values into the formula:
Work = 15N × 3m × cos(0°)
Step 3: Simplify the cosine of 0°:
cos(0°) = 1
Work = 15N × 3m × 1
Step 4: Multiply to find the work:
Work = 45J
So, the work done when a 15N force pushes a car for a distance of 3m is 45 joules.
To calculate the work done when a 15N force pushes a car for 3m, you can use the formula:
Work = Force x Distance
Here are the steps to solve the problem:
1. Identify the given values:
- Force (F) = 15N
- Distance (d) = 3m
2. Substitute the values into the formula:
- Work = 15N x 3m
3. Multiply the force and distance:
- Work = 45 N*m
4. Simplify the units:
- Since the unit for work is joules (J), 1 N*m = 1 J.
- Therefore, Work = 45 J.
So, the work done when a 15N force pushes a car for 3m is 45 Joules (J).
