Answer:
Option B. 0.6 seconds
Step-by-step explanation:
As given in the table at time t = 0 the maximum height of the penny is 2 meters.
In simpler way we can say the penny has been throw from a height of 2 meters.
Now this process can be represented by the equation of motion
[tex]h=ut+\frac{1}{2}gt^{2}[/tex]
For free fall u = 0
So [tex]h=\frac{1}{2}gt^{2}[/tex]
where h = 2 meters
and g = 9.81 m/sec²
By putting these values in the equation
[tex]2=\frac{1}{2}(9.81)(t)^{2}=4.905t^{2}[/tex]
[tex]t^{2}=\frac{2}{4.905}=0.4077[/tex]
t = √0.4077 = 0.6385 seconds
or t = 0.6 seconds
Answer is option B. 0.6 seconds
