Question

find the velocity and acceleration of the process: x=10e-2t.cos (5t + π/2)

Answer 1

velocity is first derivative, acceleration the second derivative

Answer 2

^ assuming this is a displacement vector.

Answer 3

ok

Answer 4

pls help solve the first and second derivative

Answer 5

thanks @ satellite. I have class now. take care

Answer 6

@satellite73

Answer 7

\[x'= \frac{1}{10}(-5 t \cos(5 t) - \sin(5 t))\]
\[x''= \frac52 t \sin(5 t)-\cos(5 t)\]

Answer 8

thanks

Answer 9

x=t.e-t2/2
