When you see a traffic light turn red, you apply the brakes until you come to a stop. if your initial speed was 14 m/s, and you
were heading due north, what was your average velocity during braking?
1 answer:
Average v = (initial v + final v)/2
= (14 m/s + 0 m/s)/2
= 7 m/s
Your average velocity during braking is 7 m/s

I think the answer may be the letter B
Answer:
we could use the formula, v=u+at,
65=25+a (10), a=4 , since the motion is declerating we have a=-4 m/s2
C. Radiosonde is the answer
the above mentioned is not correct
Answer:
<u>4 m/s²</u>
Explanation:
<u>Formula</u>
- Weight = Mass x Gravity due to acceleration
<u>Solving</u> :
- 400 N = 100 kg x g
- g = 400/100
- g = <u>4 m/s²</u>
Answer:
table 1:
1. 100/15 = 6.7 m/s
2. 100/12 = 8.3 m/s
3. 100/9 = 11.1 m/s
table 2:
1. 100/8 = 12.5 m/s
2. 100/6 = 16.7 m/s
3. 100/4 = 25 m/s
