Question

Figure gives the velocity–time graph. This shows that the body is

• A. moving with uniform acceleration
• B. having same initial and final velocity
• C. starting from rest and moving with uniform velocity
• D. moving with uniform retardation

Answer 1

The correct option is D moving with uniform retardation

This is the condition when an object is thrown vertically upward with a velocity under the effect of $g$.
Slope of graph is constant and negative which represent instantaneous acceleration i.e., body is moving with uniform retardation.
