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) gt T_(1)`

B

`T_(1) = T_(2)`

C

`u_(1) gt u_(2)`

D

`u_(1) lt u_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
Maximum height and time of height depends upon the vertical component of initial velocity.
`H_(1) gt H_(2) rArr u_(y_(1)) gt u_(y_(2))`
Range `R_(2) gt R_(1)`
So, `u_(2) gt u_(1)`
