Its the drop zone in kings dominion
d = 82.9 m
initial velocity = 0
final velocity (before the brakes are applied) = 32.19 m/s
i know there is gravity downward and airresistance upward.
I need to find the mass of the object.
First i found the acceleration using
v12= v02 + at
a = 6.25 m/s2
And i am confused since air resistance is directly proportional to objects velocity. Is the acceleration i found is the final acceleration before the brakes are applied or is it the average acceleration.
The Attempt at a Solution
I need to find the mass but i cant think of any way to start.
Any help is appreciated
