Problem 4-12 - Vector components
A car is travelling along a winding highway at a constant speed of \(82\; km/h.\) At 3:00 p.m., the car is heading \(38.2^\circ\) east of north, and at 3:15 p.m. it is heading \(12.7^\circ\) south of east. Define the \(+x\) and \(+y\) directions to be east and north, respectively. Use Eq. 4-8 to determine the \(x\)- and \(y\)-components of the average acceleration during this time interval.
We will work in standard units i.e., \(m\) and \(s\) so \(82\; km/hr\) is:
(A) \(22.8\; m/s\)
(B) \(295\; m/s\)
(C) \(82\; m/s\)
