4. how many credits does it take to be classified as a tenth-grade student?

If all classes (approximately six classes are taken each year) are successfully passed, you earn three credits each semester, or six credits a year. You would go into 10th grade with six credits and finish the year with twelve credits.

Hopefully this is still helpful for you. Have a good day!

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
