question 60

Multiple Choice

In an experiment, students measured the speed s (in meters per second) of a falling object $t$ seconds after it was released. The results are shown in the table below. Use the model $s = 11.9 t + 4.8$ to estimate the speed of the object after $1.5$ seconds. Round your answer to two decimal places.
$\begin{array}{|c|c|c|c|c|c|}\hline t & 0 & 1 & 2 & 3 & 4 \\\hline s & 0 & 22.0 & 30.4 & 40.2 & 50.4 \\\hline\end{array}$

• A) \(21.05\) meters/second
• B) \(20.95 \mathrm {~meters} / \mathrm { second }\)
• C) \(24.25 \mathrm {~meters} / \mathrm { second }\)
• D) \(23.55\) meters/second
• E) \(22.65\) meters/second
