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>
Standard form:
Y - 0= 1(x - 1)
Y - 0= x - 1
-x+y= -1
- (-x+y= -1)
Answer:
x-y=1
Slope-Intercept form:
Y - 0= 1(x-1)
Y - 0 = x - 1
Answer:
Y= x-1
