If a ball is thrown vertically upwards with a velocity of `40m//s`, then velocity of the ball after `2s` will be `(g = 10m//s^(2))`

Text Solution

Verified by Experts

Initial velocity (u) = 40 m/s
Acceleration `(a)=-gm//s^(2)=-10m//s^(2)`
Time (t) =2 seconds
By Ist equation of motion
`v=u+at`
`v=40-10(2)=20m//s`
