...then....then.... physics help!!!!? The instruments attached to a weather bal-
loon have a mass of 4 kg. The balloon is
released and exerts an upward force of 91.7 N
on the instruments.
The acceleration of gravity is 9.8 m/s2 .
What is the acceleration of the balloon and
the instruments? Answer in units of m/s2.
And then
After the balloon has accelerated for 13.8 s,
the instruments are released.
What is the velocity of the instruments at
the moment of their release? Answer in units
of m/s.
and then
Assume: The upward direction is positive.
What net force acts on the instruments
after their release? Answer in units of N.
and then
How long after their release does the direc-
tion of their velocity first become downward
(negative)? Answer in units of s.
