Question

In the given velocity-time graph, $AB$ shows that the body has:

• A. Uniform velocity
• B. Non-uniform retardation
• C. Non-uniform acceleration
• D. Uniform retardation

Answer 1

The correct option is D

Uniform retardation

​

From the above graph, we can see that the body has some initial velocity and the velocity is decreasing as the time increases and the final velocity is zero.

The slope of velocity-time graph gives acceleration. Since, the given velocity-time graph is a straight line with negative slope, the body is said to be in uniform retardation motion.
