How is this equation homogenic? We have s in meters and t in seconds so u say meters=1/s^2?
-8/a^3, -8, -1, -8/27 metres per second
steam is caliber, skins plz
If you differentiate the displacement equation with respect to t, you'll get the velocity equation v(t) = -8/t^3
Substitute in the values for t and there you go.
Notice that the velocity is strictly decreasing and will eventually reach 0, this is logical since from the displacement equation as t approaches infinity, the displacement also tends towards 0.
