Question

hey could you please solve this question 100% correct with no mistakes. also could you solve it handwritten for me to better understand.

The position of an object (in metres) is given by the function s(t) = t4 - 10t³ +35t² - 50t
+ 24 where t is in seconds.
a. Determine the velocity and acceleration functions for the object
b. Determine the position, velocity and acceleration of the object at t = 3.5 s.
c. At t = 3.5 s is the object to the left or right of the origin? Explain how you know.
d. At t = 3.5 s is the object travelling to the left or right? Explain how you know.
e. At t = 3.5 s is the object speeding up or slowing down? Explain how you know.
