Explain the shape of yourgraph.(b) If, when travelling at this maximumspeed, the 1000 kg car had struck andremained attached to a stationary vehicleof mass 1500 kg, with what speed wouldthe interlocked vehicles have travelledimmediately after collision?Calculate the kinetic energy of the car justprior to this collision and the kineticenergy of the interlocked vehicles justafterwards. Comment upon the valuesobtained.Explain how certain design features in amodern car help to protect the driver of acar in such a collision.[L] A60 (a) A cur of mass 1000 kg is initiolly at rest. Itmoves along a straight road for 20 s andthen comes to rest again. The speed-timegraph for the movement is:vims2010101520 ts(i) What is the total distance travelled?(ii) What resultant force acts on the carduring the part of the motionrepresented by CD?(ii) What is the momentum of the carwhen it has reached its maximumspeed? Use this momentum value tofind the constant resultant acceler-ating force.
