Question

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))

Answer 1

Answer:

Explanation:

S= ut + 1/2at^2

Given that t = 2 and a = 10 so

S = 60m

Then v^2 - u^2 = 2as

Put s = 60 , v=40 a =10 then

u =20

So the velocity is 2
