The acceleration can be calculated using the formula:
acceleration = (final velocity - initial velocity) / time
Given:
initial velocity (u) = 16.0 m/s east
final velocity (v) = 6.0 m/s east
time (t) = 4.0 s
Acceleration = (6.0 - 16.0) / 4.0 = (-10.0) / 4.0 = -2.5 m/s^2
Therefore, the acceleration of the car during this 4.0 second interval is -2.5 m/s^2 east (because it is slowing down).
