1. The problem statement, all variables and given/known data A particle starts from rest and accelerates as shown in the attached figure. Determine (a) the article's speed at t=10s and t=20s. (b) The distance traveled in the first 20s. 2. Relevant equations a=dv/dt 3. The attempt at a solution (a) t=10s, speed = 20m/s t=20s, speed = 5m/s Those were obtained by taking the area under the acceleration. (b) book gives the answer 262m. NO idea how this came about. I thought about 225m being the answer since 20m/s * 10s + 5m/s * 5s, but this wouldn't be correct because the velocity is changing, not constant. Any help would be appreciated.
