Problema Solution
The velocity (v) of a falling object is directly proportional to the time (t)of the fall. If, after 2 seconds, the velocity of the object is 64 feet per second, what will is its velocity be after 3 seconds?
Answer provided by our tutors
We assume that the relation between v and t is
v = a*t, a is constant
v = 64, t=2, so a = 32
So
v = 32t
when t=3, v = 32*3 = 96 feet per second
the velocity of the object is 96 feet per secondafter 3 seconds
