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: The tenth term in the sequence is 512.
Step-by-step explanation:
Since we have given that
We need to find the tenth term:
It means n = 10
So, it becomes
Hence, the tenth term in the sequence is 512.
Order doesn't mater so use combinations:
6C3 = 6!/ (3! (6-3)! ) = 6! /(3!*3!) = 6*5*4*3! / (3! 3!) = 6*5*4/3*2*1) = 20
Since 7 yd is 21 ft you will have to
add 15 ft to 21 ft (36 ft)
and then divide by two
your answer is 18 ft
