Answer:
The velocity of the release is 4.9 m/s.
Explanation:
Susan catches the dough, at the point of the release only therefore, the displacement of the piece of dough is 0 and the total time elapsed is 1s.
The gravity exerted will be only due to gravity as air resistance is neglected, so lets' assign downwards direction as negative and the gravity will come out to be -g.
We have to apply Second Equation of Motion which states that,
s=0
t=1
a=-g=-9.8
u=??
Plugging in the values, we get
0=u-4.9
u=4.9 m/s
Therefore, the velocity of the release is 4.9 m/s
