Question

3. The velocity-time graph of moving object is given in the figure.
Sketch the a) Acceleration-time graph
b) displacement-time graph
c) Find the distance travelled during the time interval when the
acceleration is maximum.
​

Answer 1

Answer:

c find the distance travelled during the

time interval when the acceleration is maximum

Answer 2

Explanation:

Between time interval 20 s te 40 s, there is non-zero acceleration and retardation. Hence, distance travelled during this interval

= Area between time interval 20 s to 40 s

=21×20×3+20×1=30+20=50m
