Answer allquestions in this section.

1. A student carries out an experiment to study the relationship between the speed, v,

of a trolley and the distance of compression, e, of a sprin that will push the trolley

down the track after the compression of the sprin is released.

A friction!compensated runway and a ticker!timer with its accessories are set up as shown in "iaram 1. #he trolley is pushed back to compress the sprin with a

compression, e, of 1.$ cm.

#he trolley is released. %t mo&es at constant &elocity, v, down the runway, after it is

pushed by the compressed sprin.

"iaram 1

#he procedure is repeated with compression &alues of e, 2.$ cm, '.$ cm, .$ cm and .$ cm.

#he ticker tapes are shown in "iarams 2 (a), (b), (c), (d) and (e) respecti&ely.

#he &elocity,v , of each compression can be calculated by usin the formula *

v+ cms!1

in which x is the distance co&ered in an inter&al of 1$ ticks.

An example is shown in "iaram 2(a).

-iure 1.1 (a) shows a horse pullin a carriae. -iure 1.1 (b) shows another horse of the same

strenth bein added to pull the same carriae. %t is obser&ed that in the case of fiure 1.1 (b) , the

carriae increases its &elocity at a faster rate.

-iure1.1

ased on the obser&ation,

(a) 4tate one inference that can be made (1)

(b) 4tate a suitable hypothesis (1)

(c) 7ith the use of apparatus such as a trolley, ticker timer and other apparatus, explain how

you can carry out an experiment to test your hypothesis.

%n your description, state clearly the followin*

(i) the aim of the experiment

(ii) the &ariables in the experiment

(iii) the list of apparatus and materials
