Answer:
![t = 0.93 s](https://tex.z-dn.net/?f=t%20%3D%200.93%20s)
Part b)
![d = 3.98 m](https://tex.z-dn.net/?f=d%20%3D%203.98%20m)
Part c)
![v_x = 4.28 m/s](https://tex.z-dn.net/?f=v_x%20%3D%204.28%20m%2Fs)
![v_y = -11.49 m/s](https://tex.z-dn.net/?f=v_y%20%3D%20-11.49%20m%2Fs)
Explanation:
The two components of the velocity of the ball is given as
![v_x = 4.9 cos29](https://tex.z-dn.net/?f=v_x%20%3D%204.9%20cos29)
![v_x = 4.28 m/s](https://tex.z-dn.net/?f=v_x%20%3D%204.28%20m%2Fs)
![v_y = 4.9 sin29](https://tex.z-dn.net/?f=v_y%20%3D%204.9%20sin29)
![v_y = 2.37 m/s](https://tex.z-dn.net/?f=v_y%20%3D%202.37%20m%2Fs)
Part a)
now we know that the displacement in y direction is given as
![\Delta y = 6.4 m](https://tex.z-dn.net/?f=%5CDelta%20y%20%3D%206.4%20m)
so we have
![\Delta y = v_y t + \frac{1}{2}gt^2](https://tex.z-dn.net/?f=%5CDelta%20y%20%3D%20v_y%20t%20%2B%20%5Cfrac%7B1%7D%7B2%7Dgt%5E2)
![6.4 = 2.37 t + 4.9 t^2](https://tex.z-dn.net/?f=6.4%20%3D%202.37%20t%20%2B%204.9%20t%5E2)
![t = 0.93 s](https://tex.z-dn.net/?f=t%20%3D%200.93%20s)
Part b)
Distance of the ball in x direction of the motion is given as
![d = v_x t](https://tex.z-dn.net/?f=d%20%3D%20v_x%20t)
![d = 4.28 \times 0.93](https://tex.z-dn.net/?f=d%20%3D%204.28%20%5Ctimes%200.93)
![d = 3.98 m](https://tex.z-dn.net/?f=d%20%3D%203.98%20m)
Part c)
In x direction the velocity will remain the same always
![v_x = 4.28 m/s](https://tex.z-dn.net/?f=v_x%20%3D%204.28%20m%2Fs)
while in Y direction we can use kinematics
![v_y = v_{oy} + at](https://tex.z-dn.net/?f=v_y%20%3D%20v_%7Boy%7D%20%2B%20at)
![v_y = -2.37 - 9.81(0.93)](https://tex.z-dn.net/?f=v_y%20%3D%20-2.37%20-%209.81%280.93%29)
![v_y = -11.49 m/s](https://tex.z-dn.net/?f=v_y%20%3D%20-11.49%20m%2Fs)
I believe the correct answer is the bottom one. Hope this helped!

Answer: True
Explanation: Metamorphism is the changing of rocks by heat and pressure. During this process, rocks change either physically and/or chemically. They change so much that they become an entirely new rock. Figure 4.22: The platy layers in this large outcrop of metamorphic rock show the effects of pressure on rocks during metamorphism.
