Theoretically, if the objects have the same mass and are moving towards each other at a speed of
, after a perfectly elastic collision, the object A is supposed to move with the same velocity in the opposite direction.
Answer:
This is True
Explanation:
I just did this exact unit in bio last week I hope this helps ;)
Answer:
650 km/hr
Explanation:
Draw a right triangle from (0.0) (Point A) down 30 degrees and to the right for a length of 750 (Point B). Then draw a line from B up to the x axis to make a right angle (Point C). Use the cosine function to find line AC, the vector portion of AB that lies of the x (East) axis. Cosine(30)= Adjacent/Hypotenuse.
Cos(30) = AC/750
750*(cos(30)) = AC
AC = 649.5 km/hr
I think it is either A or B. I’m mostly leaning towards B.
