An object with mass m = 0.6 kg is dropped from the topof the building and falls 21 m down in front of thecafe.
1.1 Calculate the speed of the object as ithits the ground and calculate the time for the fall. Neglect inthis question the air resistance.
In a more accurate calculation we need to take air resistanceinto account. In a wind tunnel the air resistance of the object hasbeen measured giving rise to an acceleration of: aair =0.03v2 where v is the speed of the object.
1.2 Now, taking air resistance into account,find the speed of the object as it hits the ground. Any integralsin your calculation should be calculated by hand!
1.3 Calculate the time of the fall when airresistance is taken into account. (You are allowed to usecalculator to calculate occurring integrals when answering thisquestion!)
