a) Find the velocity and acceleration as functions of t.

b) Find the acceleration after 1 second.

**Damon**, Sunday, February 24, 2013 at 5:36pmare you sure that is 2y^3 and not 2 t^3 ?

2 y^3 is all right, but unusual and probably not intended.

**Damon**, Sunday, February 24, 2013 at 5:39pmIf as typed, the 2y^3 has nothing to do with the velocity and acceleration

v =ds/dt = -14 t + 4

a = dv/dt = -14

If as I kind of have a hunch you mean

v = 6 t^2 - 14 t + 4

a = 12 t - 14

Thanks
