A student investigates their reaction time using the ruler drop test. The mean distance the ruler fell before being caught by their non-dominant hand was 15.8 cm.
Calculate the average reaction time for the non-dominant hand. Give your answer to 2 significant figures.
Use the equation:
time2=distance500 \text{time}^2 = \frac{\text{distance}}{500} time2=500distance39 exam-style questions on Edexcel GCSE Physics 2.5 Stopping and braking distances. Each one has a worked solution and a mark scheme showing where the marks go.
