Hello, I need some help with physics. Topic: collisions. Thank you!

Question1 ( ZPoints ) Consider a circle-circle collision, where both circles are identical and are able to move. The coefficient of resititution is 0.842. Ball A has an initial velocity of {0.08. 6.54] pros and is centred at pixel position [4.02, 3.56} at the moment of impact. Ball B is stationary and is centred at pixel position [0.9. 4331} at the moment of impact. Calculate the magnitude of the change in velocity along the normal for ball A or B [ignoring fn'ction]. Note that this isjust a number. not a vector. Leave your answer accurate to 2 decimal places.

Calculate the vector vf given the following equations: vf = vi + 2F P = {vi dot NIH and the following vector values: vi = {-30. 40} N = {-D.6. 0.8} Answer: vf ={ Blank 1 .
