1.67

How long will it take a running horse to travel 260 m and attain a speed of 12 m/s from rest?

A horizontally-launched projectile arcs out and hits the ground below. The vertical displacement and the horizontal displacement are measured. What is the best equation to use to find the time the projectile was in the air?

$\Delta\overrightarrow{x}=\overrightarrow{v}_x\cdot\Delta t$

$\Delta\overrightarrow{y}=\overrightarrow{v}_{yi}\cdot\Delta t+\frac{1}{2}\cdot g\cdot\Delta t^2$

$\overrightarrow{v}_{yf}=\overrightarrow{v}_{yi}+g\cdot\Delta t$

$\Delta t=\sqrt{\frac{2\cdot\Delta\overrightarrow{y}}{g}}$
