Answer:
-2/3 ; - 3/5 ; - 1/2 ; 5/8
Step-by-step explanation:
Given that:
We could convert the numbers to decimal to obtain a better view of the values :
-2/3 = - 0.66666
5/8 = 0.625
-3/5 = - 0.6
-1 /2 = - 0.5
Negative values are always arranged first on left of a number line.
-0.66666 < - 0.6 < - 0.5 <0.625
Hence,
-2/3 ; - 3/5 ; - 1/2 ; 5/8
At the time the cannonball reaches the ground, the vertical height of the cannonball from the ground is 0, i.e. h = 0.
Thus, the time it will take the cannonball to reach the ground is given by
![-16t^2+128t=0 \\ \\ \Rightarrow t(-16t+128)=0 \\ \\ \Rightarrow t=0\ or\ -16t+128=0 \\ \\ \Rightarrow16t=128 \\ \\ \Rightarrow t= \frac{128}{16} =8](https://tex.z-dn.net/?f=-16t%5E2%2B128t%3D0%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20t%28-16t%2B128%29%3D0%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20t%3D0%5C%20or%5C%20-16t%2B128%3D0%20%5C%5C%20%20%5C%5C%20%5CRightarrow16t%3D128%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20t%3D%20%5Cfrac%7B128%7D%7B16%7D%20%3D8)
Therefore, it will take the cannonball 8 seconds to reach the ground.
