Question

If the acceleration-time graph of a body moving with uniform retardation is a straight line parallel to time axis, then

• A. Acceleration is positive
• B. Final velocity is less than the initial velocity
• C. Final velocity must be negative always
• D. Speed of the body remains constant

Answer 1

The correct option is B Final velocity is less than the initial velocity

For a uniformly retarding body, the velocity decreases at a constant rate. This signifies that the final velocity is always less than the initial velocity.
Hence, the correct answer is option (b).
