The velocity-time graph of a particle is the straight line joining (0,6)(0,6)(0,6) to (7,−8)(7,-8)(7,−8), crossing the time axis at t=3t=3t=3 s. Time is measured in seconds and velocity in m s−1^{-1}−1.
State the time at which the particle changes direction.
Find the displacement of the particle during the 7 s.
Find the total distance travelled during the 7 s.
