Answer

So, the final answer is $s=\boxed{0.6539}$ radians.

Steps

Step 1 ：The problem is asking for the angle $s$ in the interval $\left[0, \frac{\pi}{2}\right]$ such that $\cos s=0.7937$.

Step 2 ：To find this, we can use the inverse cosine function, also known as arccos.

Step 3 ：The inverse cosine of 0.7937 is approximately 0.6539288071661449 radians.

Step 4 ：Rounding to four decimal places, we get $s = 0.6539$ radians.

Step 5 ：So, the final answer is $s=\boxed{0.6539}$ radians.
