At the moment t=0t=0t=0 a particle starts moving along the xxx axis so that its velocity projection varies as vx=35cosπt cm/sv_{x}=35 \cos \pi t \mathrm{~cm} / \mathrm{s}vx=35cosπt cm/s where ttt is expressed in seconds. Find the distance that this particle covers during t=2.80 st=2.80 \mathrm{~s}t=2.80 s after the start
