Draw a graph of velocity against time for a body which starts with an initial velocity of 4 ms-1   and continues to move with an acceleration of 1.5 ms-2  for 6 s . Show how you would find  from the graph :  the distance moved in those 6 s .

t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanatio

b.transmitters send radio waves, and receivers capture radio waves.
