$(i)$ What can be depicted from the graph regarding the motion of the object ?

$(ii)$ Find the value of acceleration from the graph.

Option A

Option B

Option C

Option D

Solution

$(i)$ Uniformly retarded motion.

$(ii)$ Acceleration $=$ Slope of the graph

$=\frac{(0-50) ms ^{-1}}{(40-0) s }=\frac{-50}{40} m s ^{-2}$

$=-125 m s ^{-2}$
