Question

v²-u²=2as
20²-(25/3)²=2× 0.54×s

Find s. ​

Answer 1

${20}^{2} - {( \frac{25}{3}) }^{2} = 2 \times 0.54 \times s \\ 400 - \frac{625}{9} = 1.08 \times s \\ \frac{3600 - 625}{9} = 1.08 \times s \\ \frac{2975}{9} = 1.08 \times s \\ s = \frac{2975}{9} \div 1.08 \\ s = \frac{2975}{9} \times \frac{1}{1.08} \\ s = \frac{2975}{9 \times 1.08} \\ s = \frac{2975}{9.72} \\ s = 306.07 \: \: \: \: \: \: \: \: ans$
