1. The problem statement, all variables and given/known data The position of a particle along x-axis at time 't' is given by x=1+t-t2.The distance travelled by the particle in the first second is. A) 1m B) 2m C) 2.5m D) 3m 2. Relevant equations 3. The attempt at a solution Differentiating x wrt t we get, v=1-2t and double differentiating x wrt to t we get a=-2m/s2. I plotted a V-t graph. The velocity will be 0 at t=0.5 sec , 1 at t=0sec and -1 at t=1 sec. Finding the area under the graph I got 0.5m. Where have I gone wrong? I got 2.5m when I substituted t=0.5 in x and multiplied it by 2. But why is the graph method not working?
