Answer:
Step-by-step explanation:
a) The total distance traveled by the balloon = (100 + 60) m
= 160 metes
b) speed =

The average speed for the first flight =

= 10 m/s
c) The speed during its next flight =

= 10 m/s
d) Average speed for the entire trip =

= 10 m/s
e) Total displacement =

=

= 116.62 m
f) velocity =

Average velocity during the first 10 seconds =

= 10 m/s
g) Average velocity during the next 6 seconds =

= 10 m/s
h) Average velocity for the entire trip =

=

= 14.14 m/s
