Paper 1 H - SAMPLE SET 1 Q2
2) Figure 4 shows two students investigating their reaction times.
Student B supports his left hand on a desk.
Student A holds a ruler so that the bottom end of the ruler is between the finger and thumb of student B.
When student A releases the ruler, student B catches the ruler as quickly as he can.
The investigation is repeated with the right hand of student B.
Student B supports his left hand on a desk.
Student A holds a ruler so that the bottom end of the ruler is between the finger and thumb of student B.
When student A releases the ruler, student B catches the ruler as quickly as he can.
The investigation is repeated with the right hand of student B.
(a) The students took five results for the left hand and five results for the right hand.
Figure 5 shows their results.
Figure 5 shows their results.
(i) Calculate the average distance dropped for the right hand.
Give your answer correct to 2 significant figures. (2)

(ii) Calculate the average time for the left hand.
Use the equation (2)
Use the equation (2)
average time = ....................................................... s
(b) Explain whether any of the readings are anomalous. (2)
