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 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 the nail is 50 meters above the ground in 3.9 seconds.

Therefore, the answer is: 3.9 s

Absolute values are denoted by straight bars | |

the absolute value of a negative number will be positive
the absolute value of a positive number will be positive

$\frac{|-32|}{8} - |9 \times 2|+|4|

$
do all the math in the absolute values first
$\frac{|-32|}{8} - |18|+|4|

$
do the absolute values
$\frac{ 32}{8} - 18+4

$

can you solve it now?
