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.
vf=vi + at
The Attempt at a Solution
Found t= .3 secs
d=1/2 + at^2
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.
