A car with an initial velocity of 16.0 meters per second east slows uniformly to 6.0 meters per second east in 4.0 seconds. What is the acceleration of the car during this 4.0 second interval?

Answer 1

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).
