Answer:

Explanation:

Time for one dot = 1 /50 = .02 s

Distance between 3 rd and fourth dot is 3 cm and time taken to travel this distance is .02 s

velocity = 3 cm / .02 = 150 cm /s

Distance between 4 th and 5 th  dot is 4 cm and time taken to travel this distance is .02 s

velocity = 4 cm / .02 = 200 cm /s

change in velocity = 200 cm/s  - 150cm/s = 50 cm /s

Time taken = .02 s

Acceleration = 50 / .02 cm/s²

= 2500 cm/s²
