Which one of the following is true for a deceleration? (2.3)

  1. (a) The velocity remains constant.
  2. (b) The acceleration is negative.
  3. (c) The acceleration is in the direction opposite to the velocity.
  4. (d) The acceleration is zero.

Expert Solution
To determine
True for deceleration.

Explanation of Solution

When the velocity and acceleration are in opposite direction and velocity decreases, is termed as deceleration.

The negative acceleration can occur in two possible ways: when the object is decreasing the speed and acceleration is negative in direction.

The second is when acceleration is in opposite direction and the speed increases in opposite direction.

Conclusion:

The acceleration is in the direction opposite to the velocity when the object is decreasing the speed and acceleration is negative in direction...
