Firstly, I am sorry if this is the wrong section (I really didn't know what each section meant, but I posted here since I am beginner)
1. The problem statement, all variables and given/known data
A stone is thrown up into the air at 20m/s is accelerated constantly downwards by gravity at about 10m/s^{2}
Find the anti derivative of the acceleration
Note: I am not solving for C
2. Relevant equations
3. The attempt at a solution
The antiderivative of 20m/s is 10m/s^{2}
and the antiderivate of 10m/s is 5m/s^{2}
Neither of those match up to the answer, so I'm not sure how to arrive at the answer.
The answer in the book is v= 10t + c
Thankyou
