Problema Solution
The velocity of a falling object is directly proportional to the time of the fall. If after two seconds, the velocity of the object is 64 feet per second, what will its velocity be after 3 seconds?
Answer provided by our tutors
velocity is directly proportional to time t
lets consider a propotionality constant C
then V = C*t
after when t = 2, then V= 64, use this to find the constant C, which will come out to be 32
substitute this in the equation, you get V=32t
then after 3 seconds, V=32*3= 96 ft/second
