Question

Your team is in charge of launching a large helium weather balloon that is spherical in shape, and whose radius is 2.9 m and total mass is 13.1 kg (balloon plus helium plus equipment). (a) What is the initial upward acceleration of the balloon when it is released from sea level? (b) If the drag force on the balloon is given by the equation below, where r is the balloon radius, p is the density of air, and vis the balloon's ascension speed, calculate the terminal velocity of the ascending balloon.

Explanation / Answer

The question is nothing but apparently a combination of spaces.

I do not know if there is some technical erroe or it is actually so but what it appears is just a blank line.
