(c) Velocity: Rate of change of displacement

(d) Acceleration: Rate of change of velocity

Question 2:

The figure shows a strip of ticker tape that was pulled through a ticker timer vibrating at 50 ticks per second. What is the displacement and velocity shown by the strip of ticker tape?

Displacement = 10 cm
Velocity= Displacement Time               = 10 cm 9 ticks × 0.02 s               = 10 cm 0.18 s               =55.56  cms -1
