Question

Could you make a kinematics word problem involving uniform acceleration

Answer 1

Step-by-step explanation

an aircraft stars from the rest and accelerates at 15 m/s^2 until it takes off the end of the trip,what was the speed at the end of the 3.7 km way

use

`\begin{gathered} v^2_f=v^2_1+2ax \\ where \\ a\text{ is the acceleration} \\ \text{ x is the distance} \end{gathered}`

replace

`\begin{gathered} v^2_f=v^2_1+2ax \\ v^2_f=(0)^2+2\cdot15(m)/(s^2)\cdot(3.7\cdot1000m) \\ v^2_f=111000 \\ v_f=\sqrt[]{111000} \\ v_f=333.166\text{ }(m)/(s) \end{gathered}`

so, the final velocity is

333.16 meters per second ( wow¡, that's fast)

I hope this helps you
