S = Kt - 16t^2
<span>setting s = 550 </span>
<span>550 = Kt - 16t^2 </span>
<span>this will reach the highest point when v = 0 </span>
<span>t = K/32 </span>
<span>when t = K/32 </span>
<span>550 = K^2/32 - K^2/64 </span>
<span>K^2 = 550*64 </span>
<span>K = 187.62 ft/s</span>
Answer:
See the attachment. (All results are integers, so are correct to 6 decimal places.)
Step-by-step explanation:
The function simplifies to ...
