Answer:
vi = 14.610
Explanation:
initial velocity of the first object (vi) = 0 m/s, because it was dropped
distance (y) = -20 m
initial position (y0) = 0 m
acceleration due to gravity (g) = -9.8 m/s^2
y = 1/2 gt^2 + vi*t + y0
-20 = 1/2(-9.8)t^2 + 0 + 0
-20 = -4.9t^2
4.081 = t^2
+√4.081 = t
t = 2.020
time of second object = 2.020 - 1 = 1.020
Now we can plug in the new time to solve for vi of the second object.
y = 1/2 gt^2 + vi*t + y0
-20 = 1/2(-9.8)1.020^2 + vi*1.020 + 0
-20 = -5.098 + 1.020vi
14.902 = 1.020vi
vi = 14.610 m/s

Answer:
Move towards the wall.
Explanation:
When the balloon is kept near to the wall not touching the wall, there is a force of electrostatic attraction so that the balloon moves towards the wall and stick to it.
As there is some charge on the balloon and the wall is uncharged so the force is there due to which the balloon moves towards the wall.
