Question

a baseball is hit almost straight up in to the air with a speed of about 20m/s. How long is it in the air?​

Answer 1

Explanation:

here we have to find distance

we will use v^2=u^2+ 2as

v=0m/sec

u=20m/sec

acceleration due to gravity=9.8m/sec^2

distance(s) =?

(0) ^2 = (20)^2+2*9.8*s

0=400+19.6s

400=19.6s

s=400/19.6

s=20.40m
