initial velicity = 49m/s
final velocity = 0m/s
by first law of motion
v=u+gt
o=49+(-9.8*t)
-49=-9.8*t
-49/-9.8=t
5 sec =t
final velocity = 0m/s
by first law of motion
v=u+gt
o=49+(-9.8*t)
-49=-9.8*t
-49/-9.8=t
5 sec =t

its wrong. i asked the total time, not the ball time taken to reach max. height
