Answer 1

you didn't complete your question..what do you wnat with that equation??

Answer 2

want*

Answer 3

Answer 4

solve for what?please specify the complete question

Answer 5

\[p(t)=-5\cos 2t+8\sin 2t\]

Answer 6

solve for t

Answer 7

so when p(t)=0...

Answer 8

the rest of the question is at what time does the weightpass through the equilibrium point within the first minute
