Question

an object is projected upward of the velocity of 10m/s if g= 10m/s² find the time in which it will strike the ground​

Answer 1

ANSWER

⇒ u = 100 m/s

⇒ v = 0 m/s

⇒ g = - 10 m/s²

we should find the approximate time taken to reach the ground

so , we know that ,

v = u - gt

implies ,

t = v - u / -g

t = 0 - 100 / - 10

t = 10 seconds .

therefore the approximate time taken to reach the ground is 10 s + 10s = 20s seconds.
