The position of a particle moving along an x axis'is given by x -= 6t2 t3, where x is in meters and t is in
seconds. Determine
La) The position,
(/55 The velocity, and
(c) The acceleration of the particle at t'= 2 s.

Two masses of 3 kg and 5 kg are connected by a light string that passes over a smooth pulley as in the
following gure. Determine »
(a) The tension in the string,
(b) The acceleration of each mass,
(c) The distance each mass-moves in the rst second of m'

In an Atwoods machine, one block has a mass of 0.5 kg,
and the other a mass of 0.44 kg. The pulley, which is
mounted in horizontal frictionless bearings, has a radius
of 5 cm. When released from rest, the heavier block is
observed to fall 1 meter in 5
