How do you find the velocity, speed, and acceleration at the given value for t when given the position function for t is greater than or equal to 0, s(t)= (t^4)-10(t^3) at t=4?

Question

anonymous · Answer

velocity is the derivative, acceleration is the second derivative

anonymous · Answer

and speed is the absolute value of the  velocity, so if it turns out to be negative, make it positive

anonymous · Answer

Awesome, so I just find the velocity function and plug in 4 for t and then make it positive for speed? THANKS!
