Question

6. A player moves along the boundary of a square ground of side 50 m in 200 sec.
The magnitude of displacement of the player at then end of 11 minutes 40
\seconds from his position is
a) 50 m
b) 150 m
c) 200 m
7. An object travels 40 m in 5 sec and then another 80 m is 5 sec. What is the average
d) 50-17​

Answer 1

Step-by-step explanation:

11 min 40 seconds=700 seconds.

for 200 sec,50 m.

700 sec,175 m.

175 m. is three and a half sides covered from the starting point.So, displacement is 25 m.

average speed = Total distance by total time.

=120/10=12 m/ sec
