1. The problem statement, all variables and given/known data 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!!
