Worked Solution & Example Answer:This question is about energy transfers - Edexcel - GCSE Physics Combined Science - Question 4 - 2023 - Paper 2
Step 1
Calculate the mean speed.
Answer
To calculate the mean speed, we will first sum the measured speeds from Figure 9. The speeds recorded are 1.31 m/s, 1.27 m/s, and 1.16 m/s.
-
Sum the Speeds:
[ 1.31 + 1.27 + 1.16 = 3.74 , \text{m/s} ]
-
Calculate the Mean:
[ \text{mean speed} = \frac{3.74}{3} \approx 1.25 , \text{m/s} ]
Thus, the mean speed of the ball is approximately 1.25 m/s.
