Question

Worksheet D
destructions: Study the velocity-time
graph given, and answer the following
questions
What information does the part AB
and BC of the graph convey regarding
the velocity?
At what time is the body coming to a
halt?
Calculate the total distance travelled.
Describe such a motion from every
day experience.
Calculate the total distance travelled.
Briefly describe the whole motion.
VELOCITY (m/s)

Answer 1

Explanation:

Distance covered is equal to the area under velocity-time graph.

Distance in last two seconds s

2

=

2

1

×8×2=8 m

Total distance =

2

1

×8×(6+2)=32 m

Fraction of the distance covered by the body in the last two seconds of its motion to total distance traveled by it in all the seven seconds is 8/32=1:4
