Inelastic Collision

Calculate the combined velocity of the two gliders after collision collision from the v1i and v2i from values below using the attached equation.

M1 : 195.2g ± 0.1g 

M2: 182.8g ± 0.1g 

M1 (needle)   M2 (wax)    
Intial Velocity  0.28m/s Intial Velocity  0.0m/s  
Final Velocity  0.15m/s  Final Velocity 0.15m/s  
         
known final velocity. The momentum conservation equation reads
(m + M)ūj
(6.6)
moliMi
where f is the common final velocity of the two gliders together
