Answer:
a)-296 m/s
b)-176 m
c) 198 m
Explanation:
given data:
=-20 m/s
= 15 m/s
t = 6 s
To find
a)
b)
c) d
d) find the velocity of observer at rest in basket and rest on ground
a) <em>according to kinematic equation the displacement is given by:</em>
=
-
..............(1)
putting values in 1
=-296 m/s
negative sign is due to direction and also we choose to take off point to be the origin
b) <em>while the stone was travelling </em>
<em> for 6 s so the ballon was also travelling displacement </em>
<em> with </em>
<em> </em>
<em> =</em>
=-6*20
=-120 m
the height above the earth is given by
=
-
= -176 m
c) <em>the horizontal displacement is given by</em>
x=
=15*6=90 m
so the distance between balloon and stone is
d=
=198 m
d) the velocity component of the balloon :
1) relative to person rest in the balloon are given by
The vertical component:
=
The horizontal component:

2) relative to person rest in the earth are given by
The vertical component:

The horizontal component:
