Hello, allstar2!

The velocity function is the integral of the acceleration function.

We are told that: .

So we have: .

. . . . . . . . . . . . . .

Then we have: .

Hence: .

The position function is the integral of the velocity function.

We are told: .

So we have: .

. . . . . . . . . . . . . .

Then we have: .

Therefore: .
