2) A disk (40mm diameter and 0.2 kg mass) is dropped in the air. Consider g
= 10 m/s² and the density of air 1.2 kg/m³. Assume that the drag coefficient of the disk is
1.17. At t=0, the disk speed V = 0.
a)
What is the acceleration and distance when the ball speed reaches to
1/4V₁, where V, is the terminal speed?
b)
What would be the answer for part (a) if the falling object is
hemispherical (40mm diameter and 0.2 kg mass)? Explain
Could you use a straw to sip a drink on the moon?
O Yes. It would be no different than drinking with a straw on earth.
O Yes, and it is easier on the moon because the acceleration due to gravity on the moon is only one-sixth of that on the earth.
O No, because there is no air on the moon and, therefore, no air pressure to push the liquid up the straw.
An open vessel of water accelerates up to a 30° plane at 3 m/?2. What is the vertical component of the acceleration?
