1.	Two stones are projected from level ground. Trajectory of two stones are shown in figure. Both stones have same maximum heights above level ground as shown. Let `T_(1)` and `T_(2)` be their time of flights and `u_(1)` and `u_(2)` be their speeds of projection respectively (neglect air resistance). then A. `T_(2)gtT_(1)`B. `T_(1)=T_(2)`C. `u_(1)gtu_(2)`D. `u_(1)=u_(2)`
Answer» Correct Answer - B Since maximum heights are same, their time of flight should be same `:. T_(1)=T_(2)` Aslo, vertical components of initial velocity are same. `:.` Horizontal component of velocity of 2 gt horizontal component of velocity of 1. Hence `u_(2) gt u_(1)`
