Answer 2

$\huge\bf{Answer :}$

Option (b) Vector ✔️ is the right option.

$\huge\bf{Extra\: Information :}$

• Acceleration is considered as a vector quantity because it has both magnitude as well as direction.
• A body is said to be accelerating if it's velocity is increasing.
• A body is said to have zero acceleration if it is travelling with the uniform velocity.
• Negative acceleration is also known as decelaration or retardation.
• A body is said to be retarded or decelarated the velocity in which the body is travelling with the decreasing velocity.
• Retardation can be expressed by : change in the velocity / time taken by the object.
• If the velocity of the body is decreasing, then it's acceleration is negative.
• Average velocity is defined as the mean of final and initial velocity.
