Question

from the top of a tall building you drop two tennis balls one filled with air and the other with water. which ball reaches terminal velocity first and why​

Answer 1

Answer:as we know that terminal velocity is given by

mg/6¶nr

It shows that terminal velocity of the body is directly proportional to the weight Of the object For same radius

The lighter air filter table tennis reahes terminal velocity the first . It's mass is less for the same shape and size so the friction force of upward a resistance becomes equal to the downward force of MG Sooner, In addition to To hit The force of gravity E On the water filled table tennis ball Is larger If terminal velocity is larger And it strikes the ground first
