# What is this speed? Assume an air density of 1.2 kg/m3 and a drag coefficient for sphere of 0.47.?

A 3.0 g latex balloon is filled with 2.5 g of helium. When filled, the balloon is a 31-cm-diameter sphere. When released, the balloon accelerates upward until it reaches a terminal speed.

What is this speed? Assume an air density of 1.2 kg/m3 and a drag coefficient for sphere of 0.47.
