You throw a stone from the Earth's surface. It reaches a

1st EOM: \(v = u + a*t\). 2nd EOM: \(s = u*t + \frac{1}{2}*a*t^2\). 3rd EOM: \(v^2 = u^2 + 2*a*s\)

**maximum height**of \(10 \, \mathrm{m}\). Which of the following would you use to determine its**initial velocity**?1st EOM: \(v = u + a*t\). 2nd EOM: \(s = u*t + \frac{1}{2}*a*t^2\). 3rd EOM: \(v^2 = u^2 + 2*a*s\)

3rd EOM with \(u = 0 \, \mathrm{m/s}\), \(s = 10 \mathrm{m}\) and \(a = 9.8 \mathrm{m/s^2}\)

3rd EOM with \(v = 0 \, \mathrm{m/s}\), \(s = 10 \, \mathrm{m}\) and \(a = 9.8 \, \mathrm{m/s^2}\)

3rd EOM with \(u = 0 \, \mathrm{m/s}\), \(s = -10 \, \mathrm{m}\) and \(a = -9.8 \, \mathrm{m/s^2}\)

3rd EOM with \(v = 0 \, \mathrm{m/s}\), \(s = 10 \, \mathrm{m}\) and \(a = -9.8 \, \mathrm{m/s^2}\)
