If the velocity of a particle is given by t^2+t, then determine the acceleration of the particle when t=4.
To get from velocity to acceleration, you must derivate the velocity equation. This is because acceleration is the rate at which velocity changes so to change the velocity into acceleration it must be derived.
answer: 2t+1 ---> 2(4)+1 ---> 9m/s/s
