Two stones are projected from level grou...

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)`

Text Solution

Verified by Experts

The correct Answer is:
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)`
