An object is thrwon vertically upwards with a velocity of 60 m/s. After what time it strike the ground ? Use `g=10m//s^(2)`.

A

`-g`

B

`v_(0)`

C

`y-y_(0)`

D

`sin theta`

Text Solution

Verified by Experts

The correct Answer is:
A
By the `v_(y)-t` graph the acceletration is
`(-21)/(2.1)=-10=-g`
