Use a trapezoidal sum with seven subintervals as indicated in the
table to approximate . Using correct units, explain the
meaning of in the context of the problem.
An object in motion along the x-axis has velocity v(t) = (t + et)sin t^2 for 1
≤ t ≤ 3.
At what time, t, is the object moving to the left?
Is the speed of the object increasing or decreasing when t = 2?
Justify your answer.
At t = 1 this object’s position was x = 10. What is the position of the
object at t = 3?
