Question

Velocity - time graph for the motion of a certain body is shown above. Then the body is:

• A. moving with constant velocity.
• B. uniformly accelerated and retarded in the same direction.
• C. moving with uniform acceleration in the same direction.
• D. uniformly retarded and accelerated in opposite direction.

Answer 1

Answer: (D)

uniformly retarded and accelerated in opposite direction.

Slope of velocity gives acceleration.
Since, slope is constant & negative,
Hence, accceleration is negative (hence retardation).So, it is uniformly retarded and accelerated in the opposite direction.
