The coordinate plane shows candace's bike route from the park to her home. Each unit on the coordinate plane represents one mile. How many miles did Candace bike one her route?

11 miles

Explanation:

Total miles biked by Candace on her route = (distance from the park to Library) + (distance from the Library to School) + (distance from the School to Home)

✔️distance from the park (-3, 4) to Library (2, 4) = |-3 - 2| = 5 units = 5 miles

✔️distance from the Library (2, 4) to School (2, 1) = |4 - 1| = 3 units = 3 miles

✔️distance from the School (2, 1) to Home (5, 1) = |2 - 5| = 3 units = 3 miles

✔️Total miles biked by Candace on her route = 5 + 3 + 3 = 11 miles

ek = (m·v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) ·v2/2

ek = (200 + 250) ·2,32/2 = 450·5,29/2 = 1190,25 j
