m/s2. What
a) The first part of this velocity time graph is
practically a straight line; what does this tell us
about the acceleration of the object and,
therefore, the resultant force on the object?
b) Why does the graph start to curve?
c) The acceleration of the falling object becomes
zero at the value of velocity, A; what is this value
of velocity called?
d) When the acceleration has become zero what is
the resultant force on the object?
