 P: 550 $$0.58 = \frac{1}{2} \times 9.81 \times t^2$$ Divide both sides by 1/2: $$\frac{0.58}{\frac{1}{2}} = 9.81 \times t^2$$ Divide both sides by 9.81: $$\frac{0.58}{\frac{1}{2} \times 9.81} = t^2$$ Since dividing by 1/2 is the same as multiplying by 2: $$\frac{2 \times 0.58}{9.81} = t^2$$ Taking the square root: $$\sqrt{\frac{2 \times 0.58}{9.81}} = t$$
