Question

Given the position function s(t), s(t) = t3 − 5t, where s is measured in meters and t is in seconds, find the velocity and acceleration of the particle at t = 3 seconds.

a. 12 m/sec; 22 m/sec2
b. 22 m/sec; 18 m/sec2
c. 22 m/sec; 6 m/sec2
d. 14 m/sec; 3 m/sec2

Answer 1

@latinC

Answer 2

???

Answer 3

hold on

Answer 4

is there any addition information

Answer 5

you want to calc s' and s''

Answer 6

no that is the entire problem

Answer 7

so far on got 6

Answer 8

not sure because I have displacement at 6m for t = 3, and the area under the graph is 9 meaning that velocity is 9m/s , so I'm thinking that maybe they didn't divide by 2 and left it as 18 m/s

Answer 9

what did you get so far

Answer 10

Do you know derivatives yet?
