1. The acceleration of a particle along a straight line is defined by a= (2t-9)m/s² where t is in seconds. At t=0,s=1m and v=10m/s. When t=9s determine a) the particles position b) the total distance travelled and c) the velocity 2. I think: a=dv/dt; v= ds/dt 3. From a=dv/dt you integrate and get v; from v=ds/dt you integrate and get s Then you put in for t=9s and get the result. but probably i failed the integration, what is the value of the constant you get from the integrations?
