You may not need to use all of the materials provided.

2 In this experiment, you will investigate the rolling of a sphere along tracks of different widths.

(a) (i) Measure and record the diameter d of the sphere.

d = ...........................................................[1]

(ii) • Measure and record the width w of the narrower track, as shown in Fig. 2.1.

w = ...............................................................

• Calculate D 2 where D 2 = d 2 – w 2.

D 2 = ...............................................................

(b) (i) • Place the board on the bench. Raise the end of the board with the marks by resting
it on a wooden block. Place the other wooden block across the lower end of the
board, as shown in Fig. 2.2.
Secure the blocks in position with small pieces of Blu‑Tack.

• Measure and record the distance x from the wooden block at the lower end of the
board to the mark on the middle rail, as shown in Fig. 2.3.

(d) It is suggested that the relationship between v, d and D is

d2
k = v 2 e 10 + o

where k is a constant.

(i) Using your data, calculate two values of k.

first value of k = ...............................................................

second value of k = ...............................................................
