Question

An object is moving with a constant velocity of 278 m/s. How long will it take it to travel 7500 m, using the formula Delta X=Vt+1/2at^2

Answer 1

If the velocity is constant then the acceleration of the object is zero.

`a=0 (m/s^2)`
Thus when we apply the equation

`\Delta X=vt+(at^2/2)`
It remains

`\Delta X =vt`
or equivalent

`t=(\Delta X/v) =7500/278 =26.98 (seconds)`
