How do I solve this question: Consider the position function s(t)= (t)/(t²+4), where t is greater than or equal to 0. Here s is in feet and t is in seconds.

a) Find the velocity and acceleration functions.

b) Find the position, velocity, speed and acceleration at time t=1.

c) At what times is the particle stopped.

d) When is the particle speeding up? Slowing down?

e) Find the total distance traveled by the particle from t=0 to t=5.
