1 A particle rests in equilibrium at a point O on a smooth horizontal plane.
The particle is acted upon by four horizontal forces of magnitude 6N, 10N, RN and SN. The
direction of each of these forces relative to the horizontal axes Ox and Oy is shown in Fig. 1.

There are 24 books on a bookshelf, 16 of which are poetry books and the rest are drama
books.
Eighteen of the books on the shelf are paperback and 12 of these are poetry books.
The rest of the books on the shelf are hardback.
(i) Complete Table 3 in your Supplementary Answer Booklet to show the number of poetry
books and the number of drama books on this shelf. [1]
Two students each take a book at random from this shelf.…read more

A box of mass 8kg, initially at rest, is pulled in a straight line along a rough horizontal plane
by a light inextensible rope which is held parallel to the plane. The box moves with constant
acceleration.
After travelling 18m along the plane the box is moving with velocity 3m/s.
(i) Show that the acceleration of the box is 0.25m/s2. [1]
The tension in the rope is 26N, as shown in Fig. 4.

Two packages A and B of masses 5kg and mkg respectively, where m 5, are connected by
a light inextensible string which passes over a smooth pulley fixed to the ceiling of a store, as
shown in Fig. 7.

The packages are held so that both parts of the string are hanging vertically with the string
taut. The system is released from rest and the magnitude of the acceleration of each package
during the subsequent motion is 2.5 m/s2.…read more

11 A car and a motorcycle are travelling in the same direction along a dual carriageway. At the
same instant they pass a sign warning them of a checkpoint ahead.
The car passes the warning sign at a speed of 20m/s, continues at this speed for 1 minute and
then decelerates uniformly to rest at the checkpoint.…read more
