Question:<em> </em><em>Find, separately, them mass of the balloon and the basket (incidentally, most of the balloon's mass is air)</em>
Answer:
The mass of the balloon is 2295 kg, and the mass of the basket is 301 kg.
Explanation:
Let us call the mass of the balloon and the mass of the basket , then according to newton's second law:
,
where is the upward acceleration, and is the net propelling force (counts the gravitational force).
Also, the tension in the rope is 79.8 N more than the basket's weight; therefore,
and this tension must equal
Combining equations (2) and (3) we get:
since , we have
Putting this into equation (1) and substituting the numerical values of and , we get:
Thus, the mass of the balloon and the basket is 2295 kg and 301 kg respectively.
The answer is A 0 degrees is the freezing point of water
