4-12.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°
east of north, and at 3:15
p.m. it is heading 12.7°
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.
No. They are not the same
numerically.
Remember there are 60×60 = 3600 s in 1 hr.
