When does the particle first come to rest after t=0
Malay's solution of 11pi/18 is approximately 1.92 so I'd say you made an error somewhere. Malay's method looks fine to me.Originally Posted by nath_quam
Edit: Now that I look at it, I wonder if Malay should've set it equal to pi since that's the next time it equals 0.
You're correct Nath, it first comes to rest(assuming it's moving along the positive x-axis) at
Left of the y-axis, it first comes to rest at
Add or subtract multiples of to arrive at any subsequent extrema. The corresponding y values are -2 or 2.
