A baseball thrown vertically with a speed of 3m/s. Find the total time that the ball has been in flight when it had traveled 50cm.

2. Relevant equations

vf=vi + at

d= 1/2at^2

3. The attempt at a solution

Found t.

vf=vi +at

vf=3

vi=0

a=~10

Found t= .3 secs

Found d

d=1/2 + at^2

d=4.5m

Added 4.5m to .5m =5m

Plugged in total distance 5m into d=1/2 + at^2

Found t= 1

Added 1+.3 to get total time of 1.3 secs.

The answer in the manual is 0.398 sec.

I am way off can someone please help. Thanks!!
