A) 100 meters
B) 320 meters
C) 80 meters
D) 240 meters
Correct Answer: C
Solution :
Let both balls meet at point P after time t. The distance travelled by ball \[A,{{h}_{1}}=\frac{1}{2}g{{t}^{2}}\] The distance travelled by ball \[B,{{h}_{2}}=ut-\frac{1}{2}g{{t}^{2}}\] \[{{h}_{1}}+{{h}_{2}}=40\,m\] \[\Rightarrow \]\[ut=400,t=400/50=8\,m\] \[\therefore \]\[{{h}_{1}}=320\,m\]and\[{{h}_{2}}=80\,m\]You need to login to perform this action.
