Question

s(t)= 1.85sin(36piet) t= seconds find velocity for t=0.025sec

Answer 1

\[v(t)=1.85*36pisin(36\pi t)\]
\[v(0.025)=1.85*36\pi \sin(36 \pi 0.025)\]
pi = 3.14

Answer 2

sorry!!!!

Answer 3

\[v(0.025)=1.85*36 \pi \cos(36 \pi 0.025)\]

Answer 4

??

Answer 5

derivative of sin is cos

Answer 6

what is your problem now??

Answer 7

why is it(36*pie-cos)

Answer 8

\[d(\sin(at))/dt=a \cos(at)\]

Answer 9

so where do i go from there

Answer 10

s(t) is a distance function, so the velocity is derivative of s(t) \[v(t)=ds(t)/dt\]

Answer 11

Answer 12

how can i get my answer is cm/s

Answer 13

Since your question doesnt involve any distances, you can choose your time interval to be 1 cm per 1 second (t).
