The football has a mass of 0.42 kg - Edexcel - GCSE Physics - Question 3 - 2023 - Paper 1

To find the height, we can rearrange the gravitational potential energy equation:

$\Delta h = \frac{\Delta GPE}{m \times g}$

Substituting the values into the equation:

$\Delta h = \frac{11 \text{ J}}{0.42 \text{ kg} \times 10 \text{ N/kg}}$

Calculating the denominator gives:

$0.42 \times 10 = 4.2 \text{ N}$

Hence:

$\Delta h = \frac{11}{4.2} \approx 2.619 \text{ m}$

Rounding to two decimal places, we find:

$\Delta h \approx 2.6 \text{ m}$
