Here's how to calculate the force needed:
1. Understand the Concept:
* Newton's Second Law of Motion: This law states that the force (F) acting on an object is equal to its mass (m) multiplied by its acceleration (a). Mathematically, this is: F = m * a
2. Convert Units:
* Acceleration: You need to convert 4.2 minutes per second into meters per second squared (m/s²). This conversion involves multiple steps and is not straightforward. It's likely there's a typo in the problem.
3. Apply the Formula:
* Assuming a valid acceleration: If you have the correct acceleration value in m/s², you can simply plug the mass and acceleration into the formula F = m * a.
Example:
Let's assume the acceleration is 4.2 m/s² (for demonstration purposes).
* F = 70 kg * 4.2 m/s²
* F = 294 Newtons (N)
Therefore, to accelerate a 70 kg object at a rate of 4.2 m/s², a force of 294 Newtons is required.
Important Note: Please double-check the acceleration value in your problem. If it's meant to be a different unit, let me know and I can help you with the calculation.
