QUESTION:
A bicyclist has the position-versus-time graph shown in Figure P2.9 . What is the bicyclist’s velocity at t = 10 s, at t = 25 s, and at t = 35 s?
ANSWER:Step 1 of 3
Calculating the slope of the velocity line 1 which is the velocity of the bicycle \(v_{1}\) at \(t_{1}\) as:
\(\begin{array}{l}
v_{1}=\frac{75-50}{10-0} \\
=2.5 \mathrm{~m} / \mathrm{s}
\end{array}\)
Thus, the velocity of the bicycle at 10 sec is \(2.5 \mathrm{~m} / \mathrm{s}\)
