(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The motion of a particle is given by x=(6.0m) cos(0.586t +0.72)

a) find amplitude

b) find period

c) find the first time for t>0 when v=0

d) find the max acceleration

e) find the phase at time t = 1.38s

2. Relevant equations

T = 2pie/omega

v = -A omega sin omega*t

a = -A omega^2 cos omega*t

3. The attempt at a solution

I got the first 2.

amplitude = 6.0m

period = 2pie/omega = 10.7s

i'm not sure about the next 3:

for c) do i use the second equation above and make v = 0 and just solve for t?

for d) do i use the third equation? but what do i use for t?

e) Phase is looking for the angle, right?

Can someone please help me with the last 3?

THANKS!
