Question

An object mass 4kg is dropped downwards. it experiences a resistance of 0.3v^2 N. Determine its terminal velocity.​

Answer 1

Multiply the height by 2, and divide the result by the object's acceleration due to gravity. If the object fell from 5 m, the equation would look like this: (2*5 m)/(9.8 m/s^2) =1.02 s^2. Take the square root of the result to calculate the time it takes for the object to drop.
