A particle moves according to a law of motion s = f(t) = te-t / 5, t 0, where t is measured in seconds and s in feet.
(a) Find the velocity at time t.
v(t) = $$
ft/s
(b) What is the velocity after 4 s? (Round the answers to three decimal places.)
v(4) = 0.08986579 ft/s
(c) When is the particle at rest?
t = 5 s
(d) When is the particle moving in the positive direction? (If you need to use -∞ or ∞, enter -INFINITY or INFINITY.)
(0 , INFINITY )
(e) Find the total distance traveled during the first 12 s.
(No Response) feet
(f) Draw a diagram to illustrate the motion of the particle. (Do this on paper. Your instructor may ask you to turn in this graph.)
(g) Find the acceleration at time t and after 4 s. (Round the second answers to three decimal places.)
a(t) = $$
a(4) = (No Response) ft/s2
(h) Graph the position, velocity, and acceleration functions for t 0. (Do this on paper. Your instructor may ask you to turn in this graph.)
(i) When is the particle speeding up? (If you need to use -∞ or ∞, enter -INFINITY or INFINITY.)
(0 , 5 )
When is it slowing down?
if someone can help I really appreciate it. Have a great day

Read the excerpt from the strange case of dr jekyll and mr. hyde what do dr. jekyll's thoughts reveal about him in this excerpt? [t]he inmates of my house were locked in the most rigorous hours of slumber, and i determined, flushed as i was with hope and triumph, to venture in my new shape as far as to my bedroom. i crossed the yard, wherein the constellations looked down upon me, i could have thought, with wonder, the first creature of that sort that their unsleeping vigilance had yet disclosed to he is jealous of those who can sleep through the night. he is revered for his scientific advances. he is interested in studying the movements of the stars he is proud and enthusiastic about his initial results.
