Question

If an object moves along the y-axis (marked in feet) so that its position at time x (in seconds) is given by

f(x)= 255x-17x^2 , find the following

A. The instantaneous velocity function v=f'(x)
B. The velocity when x=0 and x=1 sec
C. the time(s) when v=0

Answer 1

For b you will substitute your x values for 0 and the. 1

For c make you're velocity o and use the quadratic formula and you will find your x values
