a racecar starts from rest and accelerates at a constant rate of 11.0 m/s². how fast is the racecar traveling 3.00 s later?
16.5 m/s
99.0 m/s
33.0 m/s
49.5 m/s

Explanation:

Step1: Recall the kinematic equation

For an object starting from rest (\(u = 0\)) with constant acceleration \(a\), the final velocity \(v\) after time \(t\) is given by the equation \(v=u + at\).

Step2: Substitute the given values

Here, \(u = 0\space m/s\) (starts from rest), \(a = 11.0\space m/s^{2}\), and \(t = 3.00\space s\). Substituting these values into the equation: \(v=0+(11.0\space m/s^{2})\times(3.00\space s)\).

Step3: Calculate the final velocity

\(v = 11.0\times3.00\space m/s=33.0\space m/s\).

Answer:

33.0 m/s (corresponding to the option "33.0 m/s")
