1. As you can see in the graph attached, the x axis represents the time in seconds and the y axis represents the height in meters.
2. Therefore, to solve this exercise and calculate <span>how many seconds is the nail 50 m above the ground, you must draw a segment from 50 meters to the curve and then, you need to draw another segment from that point at the curve, to the x axis, as it is shown in the figure attached.
3. You can conclude that </span>the nail is 50 meters above the ground<span> in 3.9 seconds.
Therefore, the answer is: 3.9 s</span>
Answer:
You put 19 instead of 3:)

Answer:
21.38
Step-by-step explanation:
Find the diagram attached
In order to get PS, we need to get the length of QS first
According to triangle QRS;
QS =opposite
QR = 39(adjacent)
Using SOH CAH TOA
Tan theta = opp/adj
Tan 28 = QS/39
QS = 39tan28
QS = 39(0.5317)
QS = 20.74
Get PS
sin theta = QS/PS
sin 76 = 20.74/PS
PS = 20.74/sin76
PS = 20.74/0.9703
PS = 21.38
Hence the length of PS is 21.38
