Question

How much force would it take to push Ms. Edmonds, who has a mass of 70 kg, to accelerate at 4 m/s²?

a. 70 N
b. 140 N
c. 210 N
d. 280 N

Answer 1

To push Ms. Edmonds to accelerate at 4 m/s², a force of 280 N would be needed.

Step-by-step explanation:

To calculate the force needed to accelerate an object, we can use Newton's second law of motion, which states that the force is equal to the mass of the object multiplied by its acceleration. In this case, the mass of Ms. Edmonds is 70 kg and the acceleration is 4 m/s². So, the force needed would be:

Force = Mass x Acceleration

Force = 70 kg x 4 m/s²

Force = 280 N

Therefore, it would take a force of 280 N to push Ms. Edmonds to accelerate at 4 m/s².
