Question

The acceleration of an object can be described by the equation a=2d/t^2, where a is acceleration d is the distance, and t is time. if an object accelerates at a rate of 2(m/s^2) for 10 meters what is the total time elapsed?

Answer 1

the main formula is
a=2d/t^2, so we can deduce that t^2=2d / a, and t=sqrt(2d/a)
for a=2(m/s^2), d=10 meters,
so t=sqrt(2x10/2)=sqrt(10) s
