Answer:
Ficus trees are warm-weather, tropical trees. Varieties include the fruit-producing fig, the houseplant Ficus benjamina, and the rubber plant. Whether you grow ficus trees in the landscape or in the home, providing the right temperature is vital to prevent damage and ensure good, healthy growth on the tree.
Explanation:
Answer:
V = wavelength * frequency = 1.5 * 5.5 = 8.25 m/s
The acceleration of the baseball is:
![a= \frac{v_f-v_i}{\Delta t}](https://tex.z-dn.net/?f=a%3D%20%5Cfrac%7Bv_f-v_i%7D%7B%5CDelta%20t%7D%20)
where
![v_f](https://tex.z-dn.net/?f=v_f)
and
![v_i](https://tex.z-dn.net/?f=v_i)
are the final and initial speed of the ball, and
![\Delta t](https://tex.z-dn.net/?f=%5CDelta%20t)
is the time interval in which the force acted.
Replacing the numbers, we get
![a= \frac{30 m/s-0m/s}{0.5 s}=60 m/s^2](https://tex.z-dn.net/?f=a%3D%20%5Cfrac%7B30%20m%2Fs-0m%2Fs%7D%7B0.5%20s%7D%3D60%20m%2Fs%5E2%20)
And at this point, we can use Newton's second law F=ma to find the value of the force of the pitching machine:
