Answer:
35.28m/s; 63.50m
Explanation:
<u>Given the following data;</u>
Time, t = 3.6 secs
Since it's a free fall, acceleration due to gravity = 9.8m/s²
Initial velocity, u = 0
To find the final velocity, we would use the first equation of motion;
Substituting into the equation, we have;
V = 35.28m/s
Therefore, the final velocity of the penny is 35.28m/s.
To find the height, we would use the second equation of motion;
![S = ut + \frac {1}{2}at^{2}](https://tex.z-dn.net/?f=%20S%20%3D%20ut%20%2B%20%5Cfrac%20%7B1%7D%7B2%7Dat%5E%7B2%7D)
Substituting the values into the equation;
![S = 0(3.6) + \frac {1}{2}*9.8*(3.6)^{2}](https://tex.z-dn.net/?f=%20S%20%3D%200%283.6%29%20%2B%20%5Cfrac%20%7B1%7D%7B2%7D%2A9.8%2A%283.6%29%5E%7B2%7D)
![S = 0 + 4.9*12.86](https://tex.z-dn.net/?f=%20S%20%3D%200%20%2B%204.9%2A12.86)
![S = 0.5 *36](https://tex.z-dn.net/?f=%20S%20%3D%200.5%20%2A36)
S = 63.50m
Therefore, the height of the tower is 63.50m.
<h2>It will take 0.125 seconds to reach the net.</h2>
Explanation:
Initial speed, u = 34 ft/s = 10.36 m/s
Acceleration, a = -9.81 m/s²
Displacement, s = Final height - Initial height = 8 - 4 = 4 ft = 1.22 m
We have equation of motion, s = ut + 0.5 at²
Substituting
s = ut + 0.5 at²
1.22 = 10.36 x t + 0.5 x -9.81 x t²
4.905t² - 10.36 t + 1.22 = 0
t = 1.99 s or t = 0.125 seconds
Minimum time is 0.125 seconds.
It will take 0.125 seconds to reach the net.
