Answer:
3.53 second
Explanation:
The formula for the height is
When it hits the ground, the height is zero.
So, put h = 0 in the above equation
Take positive sign
t = 3.53 second.
Thus, the time taken to hit the ground is 3.53 second.

Answer:
Work cause a change in kinetic energy
I think the answer is Resistance. If the link i posted int he comment is right.
The velocity is 14 m/s
The parameters given on the question are
mass= 0.060 kg
kinetic energy= 5.9 joules
K.E= 1/2mv²
5.9= 1/2 × 0.060 × v²
5.9= 0.5 × 0.060v²
5.9= 003v²
v²= 5.9/0.03
v²= 196.66
v= √196.66
v= 14 m/s
Hence the velocity of the egg before it strikes the ground is 14 m/s
