Independent variable if I’m not mistaken
Answer:
a) s = 42 m
b) V = 26 m/s
c) a = 11 m/s²
Explanation:
The velocity(V) = 2 - 4t + 5t^3/2 where t is in seconds and V is in m/s
a) To get the position, we have to integrate the velocity with respect to time.
We get the position(s) from the equation:


Integrating both sides,


Integrating, we get

But at t=0, s(0) = 2 m
Therefore,

c = 2
Therefore
When t = 4,


s = 42 m
At t= 4s, the position s = 42m
b) The velocity equation is given by:

At t = 4,

V = 2 - 16 + 40 = 26 m/s
The velocity(V)at t = 4 s is 26 m/s
c) The acceleration(a) is given by:


Differentiating with respect to t,


At t = 4 s,


a = 11 m/s²
