Freight car A has a mass of 15000 kg and freight car B has a mass of 12000 kg respectively. Freight car A is moving at 20 m/s on the horizontal track when it encounters freight car 8 coasting at 15 m/s towards it as shown in the figure. The cars collide and couple together. Vragwa A het 'n massa van 15000 kg en vragwa B het 'n massa van 12000 kg, onderskeidelik. Vragwa A beweeg teen 20 m/s op die horisontale spoor wanneer dit vragwa B telkom wat hom nader teen 1.5 m/s soos aangedui in die figuur. Die waens bots en koppel aanmekaar vas. a0 Determine the speed of both cars just after the coupling Bepaal die spoed van die waens net na die koppeling. m/s b) Determine the average force between the two cars if the coupling takes 12s \ Bepaal die gemiddelde krag tussen die twee waens indien die koppeling 12s duur.
