Question

a) drive the equations for collision in one demanision
b) define principal of moments​

Answer 1

Answer:

a) In equation form, we can write this as:

K=(V2f-V1f)/(V1i-V2i), Where 1 and 2 denote the two objects, and F represents values after the collision (final) and I represents values before the collision (Initial).

b) The principal of moments states that when a boby is balances, the total clockwise moments about a point equals the total anticlockwise moments about the same point.

Answer 2

Explanation:

above one is correct and that
