b For a general velocity function v of an object moving along a line, · Sº v(t) dt is the: a distance traveled by the object over the time interval [a, b]. the position of the object at t = b. the displacement of the object over the time interval [a, b]. QUESTION 3 b If the velocity and the position of an object are v and s, respectively, then in general s (0) + f³v a the position of the object at t = b. the displacement of the object over the time interval [0, b] the distance traveled by the object over the time interval [0, b] v(t) dt is: QUESTION 10 If the substitution u = tan x is made, then du = sec²x du = sec x dx du = sec²x dx
