A) \[\frac{400}{3}\text{m}\]
B) \[\frac{500}{3}\text{m}\]
C) \[\frac{1700}{3}\text{m}\]
D) \[\text{498}\,\text{m}\]
Correct Answer: B
Solution :
[b] Time taken for vertical direction motion \[t=\sqrt{\frac{2h}{g}}=\sqrt{\frac{2\times 490}{9.8}}=\sqrt{100}=10\,s\] The same time is for horizontal direction. \[\therefore \,\,x=vt=\left( 60\times \frac{5}{18} \right)\times 10=\frac{500}{3}\text{ m}\]You need to login to perform this action.
