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. - 120 -130arrow_forward
