Question 27

A motorised buggy travels in a straight line and pulls a tape through a ticker timer. Adjacent dots are made 0.020 s apart. On one section of the tape, five consecutive time intervals cover 4.0 cm. On a later section, five consecutive time intervals cover 7.0 cm. The times at the centres of the two sections are 0.30 s apart.

What is the average acceleration of the buggy between these two speed measurements?
