Problems
In Exercises 7-10, a position function 7(t) is given. Find v(t)
and a(t).
7. 7(t) = (2t+1, 5t — 2, 7)
8. 7(t) = (31²-2t+ 1, −ť² + t + 14)
9. 7(t)= (cost, sin t)
10. 7(t) = (t/10,- cost, sin t)
In Exercises 11-14, a position function 7(t) is given. Sketch
7(t) on the indicated interval. Find (t) and ä(t), then add
V(to) and a (to) to your sketch, with their initial points at 7(to),
for the given value of to.
11. F(t) = (t, sin t) on [0, π/2]; to = π/4
12. 7(t) = (t², sin t²) on [0, π/2]; to = √π/4
13. 7(t) = (t + t, -t² + 2t) on [-2, 2]; to = 1
14. 7(t) =
2t+3
t² + 1
on [-1, 1]; to = 0
In Exercises 15-24, a position function 7(t) of an object is
given. Find the speed of the object in terms of t, and find
where the speed is minimized/maximized on the indicated
interval.
