A) 0.25
B) 0.75
C) 0.5
D) 0.9
Correct Answer: C
Solution :
[c] Energy lost in the collision is \[\Delta E=\frac{1}{2}m{{u}^{2}}_{red}\left( 1-{{e}^{2}} \right)\] \[\therefore \frac{3}{16}{{\left( {{{\vec{u}}}_{1}}-{{{\vec{u}}}_{2}} \right)}^{2}}=\frac{1}{2}m{{u}^{2}}_{rel}\left( 1-{{e}^{2}} \right)\Rightarrow e=0.5\]You need to login to perform this action.
