Ocelebrate a victory, a pitcher throws her glove straight upward with an initial speed of 6.0 m/s. (a) how long does it take the glove to return tothe pitcher? (b) how long does it take for the glove to reach its maximum height?

As per the kinematics equation

when glove comes back to his hand the displacement will become zero

Part b)

Now as per symmetric nature the time to reach the top will be same as the time to come back again

so here we can say

so it took 0.61 s to reach the top
