A student drops a small black sphere alongside a vertical scale marked
in centimetres. A number of flash photographs of the sphere are taken at
0.10s intervals:
9.
..
This diagram is shown sideways- the first black dot is at 0 cm and the next
at 4 cm.
Figure 1.19
The first photograph is taken with the sphere at the top at time t = 0s.
Explain how Figure 1.19 shows that the sphere reaches a constant
speed.
Determine the constant speed reached by the sphere.
Determine the distance that the sphere has fallen when t 0.80 s.
In a real photograph, each image of the sphere appears slightly
blurred because each flash is not instantaneous and takes a time
b
of 0.0010s.
Determine the absolute uncertainty that this gives in the position of each
position of the black sphere when it is travelling at the final constant speed.
Saggest whether this should be observable on the diagram.

Please answer the following question(s):
1. The speed of a boat in still water is vá. A river flows with a speed of v₁. The boat travels
distance of 19 miles downstream in a river in 1 hour. However, the return journey takes 2
hours. Calculate the vand v₁.
Hint: Velocity=displacement/time. Displacement can be positive of neagtive depending on the
direction. You will first need to set up the equations by taking into account the resultant
velocity of the boat in flowing water. Consider the direction the river is flowing to be positive.
Set up two equations, one for the downstream journey and one for the upstream journey, in
terms of "v" and "v":
Do v" and "v, add or substract downstream to give the resultant downstream velocity?
Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the
upstream direction as negative. The resultant upstream velocity should be negative.
