Answer:
I can't really see anything in here could you make the photo up close. Please thanks, I really want to help you :)))
Step-by-step explanation:
When the car is moving, it has Kinetic Energy. As soon as the car entercount with the spring, its Kinetic Energy will transfer to Elastic Potential Energy.
<span>KE = EPE </span>
<span>1/2mv^2 = 1/2kx^2 </span>
<span>change the speed into m/s </span>
<span>50 km/hr = 13.9 m/s </span>
<span>1/2(1200)(13.9)^2 = 1/2k(2.2)^2 </span>
<span>now you do the math to solve for k.
k= 115926/2.42
K= 47903.30</span>
Answer:
where are the answer choices?
Step-by-step explanation:
It’s easier than you think, just don’t overthink it. You’re fine.
I think I’m right, but here;
5/6 + 2-2/3 = 3 1/2
Then you subtract how much the person used,
2-2/3 - 1-1/3 = 1 - 1/3 or 1.3333333 (repeated)
I think. It came out as a repeated decimal, but I just put it in fraction form.
I hope this helped :]
