Question

How much force (in pounds)required to move one ton container from stationary to one $\frac{m}{s^2}$?

• A. 220.70
• B. 222.80
• C. 224.80
• D. 225.80

Answer 1

Answer: (C)

224.80

Answer 2

For Solving this problem we use Newton's second law of motion($F=m\times a)$
Acc. to Ques:

• $m = 1000 \, \text{kg}$
• $a = 1 \, \frac{m}{s^2}$

So, $F = 1000 \, \text{kg} \cdot 1 \, \frac{m}{s^2} = 1000 \, \text{N}$
-We know that $(1 \, \text{N} \approx 0.2248 \, \text{lbs})$

$F \text{ (in pounds)} = 1000 \, \text{N} \times 0.2248 \, \frac{\text{lbs}}{\text{N}} \approx 224.8 \, \text{lbs}$

Therefore, The correct option is (C).
