A) \[{{\tan }^{-1}}(1.2)\]
B) \[{{\tan }^{-1}}(0.2)\]
C) \[{{\tan }^{-1}}(2)\]
D) \[{{\tan }^{-1}}(0.4)\]
Correct Answer: D
Solution :
[d] \[{{s}_{x}}={{v}_{0}}\sin \theta -4t=0\] \[{{v}_{0}}\sin \theta =4t\] ......(i) \[{{s}_{y}}={{v}_{0}}\cos \theta -10t=0\] \[{{v}_{0}}\cos \theta =10t\] ......(ii) From (i) &(ii), \[\tan \theta =0.4\]You need to login to perform this action.
