Question

1.There is a falling object, whose mass is A [kg] and experiences a force (its own weight) equal numerically to A times 9.81. The object starts from rest and the air causes a retarding force numerically equal to B times its velocity.

a)Find general expression for velocity as a function of time, and draw its graph.

b)Evaluate velocity for t = C (s)

Depending on your value of R choose

            R          A                    B                     C

0          6                      0.180               4              

            1          7                      0.200               5

            2          8                      0.220               6
