X 2 Final displacement. Next we must determine the acceleration of the car. Since s tt38t2-t dsdt3t216t-1.
Now the total time.
The derivative of an equation is just a different equation that tells you its slope. The instantaneous speed at t 50 s is 490 ms. Instantaneous velocity is a kind of velocity when an object travels in a given path at a constant velocity. As said earlier above this Dt has to be near zero if we want to calculate instantaneous velocity.
