The velocity is always to the line of a circle

the answer is tangent

Explanation:

tangent means a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.

hope this helps please like and heart this answer and give 5 stars and brainliest pls i beg u thx!!! : )

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
