A van of mass 1200kg was moving at a velocity of 8m/s when it was involved in a head-on collision with a lorry moving in the opposite direction. Assuming that the van came to stop after the collision,

i. calculate the momentum of the van before the collision

ii. work out the momentum of the van after the collision

iii. find the change in momentum of the van

iv. if the van took 0.3s to stop, calculate the force that acted on each driver.

Answer:

i.800kg

ii.1200kg

iii.velocity

iiii.2000kg
