Paper 4 (9164, Section B) · November 2004 · Kinematics

The diagram shows the $(t,\ x)$ graph for a particle which moves along a straight line, where x metres is the displacement of the particle from a fixed origin. Write down the final displacement of the particle, in metres.

Model answer

-2

Also accepted: -2 m, -2m, - 2, -2,0, -2.0

Explanation

The graph runs out at

t=7

s, and at that instant the curve is at

x=-2

. So the final displacement is

-2

m, that is 2 m on the negative side of the origin.

The $(t,\ x)$ graph for a particle moving along a straight line starts at $x=-4$ m when $t=0$ and finishes at $x=-2$ m when $t=7$ s, where x metres is the displacement from a fixed origin. Find the average velocity of the particle, in ms $^{-1}$ .
A particle is projected from the point O with speed 8 ms $^{-1}$ at an angle $\theta$ above the horizontal, and it passes through the point $A(8;\ -1.81)$ , distances in metres, with O as origin. Taking $g=9.81$ ms $^{-2}$ , there are two possible values of $\theta$ . Find the smaller one, in degrees, correct to 1 decimal place.
A particle is projected from O with speed 8 ms $^{-1}$ at an angle $\theta$ above the horizontal and passes through the point $A(8;\ -1.81)$ , distances in metres. The two possible values of $\theta$ are $45^{\circ}$ and $32.2^{\circ}$ . Which value gives the minimum time taken to reach A, and why?
A particle A of mass $6m$ kg rests on a rough plane inclined at $30^{\circ}$ to the horizontal, with coefficient of friction 0.25. A light inextensible string runs from A over a smooth pulley at the top of the plane to a particle B of mass $2m$ kg hanging freely. The system is released from rest. Does A slide down the plane?
A light inextensible string carrying tension T passes over a smooth pulley P fixed at the top of a plane inclined at $30^{\circ}$ to the horizontal. One part of the string runs down the slope to a particle on the plane, and the other hangs vertically. What is the magnitude of the force exerted by the string on P?
