Physics 30 - Assignment 2 2. A police car with a mass of 1400 kg is headed west at 60 km/h when it has an inelastic collision with a southbound 2000-kg ambulance. The wreckage ended up travelling at 45 km/h at 236. a) What was the initial speed of the ambulance? Include a vector diagram with your answer. (5 marks) 16 b) The above collision is classified as an _i_collision because _ii conserved, we know this because _iii (1 mark) /1 Row ii iii A elastic Momentum is The final velocity is less than the initial B elastic Kinetic energy is The vehicles stick together C inelastic Momentum is not the final velocity is less than the initial D inelastic Kinetic energy is not The vehicles stick together The letter of the row that best complete the above statement is
