Question

A graph of angular position v. time has the following equation:
y = 3.5x^2 + 25x + 250
At what angular position is the object at the beginning of the graph?

Answer 1

Answer:

3.5x^2 +25x +250-y=0 derivate this eqn you get 7x +25-1 =0 7x =-24 divided the eqn and you get it then inter the value what you get in first eqn
