total momentum after and before the collision remains same
here the total momentum will be a result of subtracted momentums as they are in opposite directions
see the pic to see the velocity of the truck
ans will be 8.545m/s=30.76km/hr
2-the change in momentum For the bus will be more as it has less mass
u can calculate to show it (optional)
m*(final velocity -initial velocity)
calculate and compare
3- the impact on the bus will be more
as it has greater change in momentum
due to its smaller mass
we know that
f=change in momentum /time
here time remains same
as change of momentum of bus is greater than truck the impact of force is more on bus
