Question

13. In fig. the displacement
of a body is shown
at different times.
Calculate the velocity of body as it moves for :-
1)0 to 5 seconds
2)5 to 7 seconds
3) 7 to 9 seconds ​

Answer 1

Answer:

so easy

Explanation:

for displacement-time graph

the slope gives the velocity

1)for 0 to 5 s

∆s=3-0=3

∆t=5-0=5

velocity=∆s/∆t=3/5=0.6m/s

2)5 to 7 seconds

∆s=3-3=0

∆t=7-5=2

velocity=∆s/∆t=0/2=0m/s

3) 7 to 9 seconds

∆s=7-3=4

∆t=9-7=2

velocity=∆s/∆t=4/2=2m/s
