Question 2.

Four movers pick up boxes. Each box has a different mass, and each mover applies a different amount of force to lift the box. Which box will have the greatest acceleration?(1 point)

A. a 10 kg box lifted with 40 N of force

B. a 20 kg box lifted with 60 N of force

C. a 20 kg box lifted with 40 N of force

D. a 10 kg box lifted with 60 N of force

I chose B. I don't know. An explanation would be nice with this as well pls!

The answer is actually D, a 10 kg box lifted with 60 N of force. This is because acceleration is determined by the ratio of force and mass (Newton's second law). In other words, the greater the force applied to a given mass, the greater the acceleration.

Using the formula F=ma (force equals mass times acceleration), we can rearrange it to solve for acceleration: a=F/m.

For each box and force combination:

A. a=40 N/10 kg=4 m/s2

B. a=60 N/20 kg=3 m/s2

C. a=40 N/20 kg=2 m/s2

D. a=60 N/10 kg=6 m/s2

Therefore, option D has the greatest acceleration.
Thank you!
