Answer:
F = 280 N
Step-by-step explanation:
To determine the force needed to accelerate a 70 kg table at a rate of 4 m/s², we can use Newton's second law of motion, which states that force (F) is equal to mass (m) times acceleration (a).
So, we can calculate the force (F) required using the following formula:
where F is the force in Newtons (N), m is the mass in kilograms (kg), and a is the acceleration in meters per second squared (m/s²).
Plugging in the given values, we get:
- F = 70 kg x 4 m/s²
- F = 280 N
Therefore, the force needed to accelerate a 70 kg table at a rate of 4 m/s² is 280 Newtons.
