Question

1. what type of acceleration occurs when a vehicle decreases speed in a positive direction? positive acceleration negative acceleration zero acceleration

Explanation:

Acceleration is the rate of change of velocity. If the vehicle is moving in the positive direction but its speed is decreasing, the change in velocity (final velocity - initial velocity) is negative. Since acceleration \(a=\frac{\Delta v}{\Delta t}\) (where \(\Delta v = v_{f}-v_{i}\)), a negative \(\Delta v\) (when \(v_{f}

Answer:

negative acceleration
