1.Give examples of a onedimensional motion where
(a) the particle moving along positive xdirection comes to rest
periodically and moves forward.
(b) the particle moving along positive xdirection comes to rest
periodically and moves backward.
2.Give example of a motion where x > 0, v < 0, a > 0 at a particular
instant.
3. An object falling through a fluid is observed to have acceleration
given by a = g – bv where g = gravitational acceleration and b is
constant. After a long time of release, it is observed to fall with
constant speed. What must be the value of constant speed?
4.A particle executes the motion described by ( ) = (1 − − t );
o x t x e γ t ≥ 0 ,
x0 > 0.
(a) Where does the particle start and with what velocity?
(b) Find maximum and minimum values of x (t), v (t), a (t). Show that
x (t) and a (t) increase with time and v (t) decreases with time.
