A4000-kg truck traveling with a velocity of 20 m/s due south collides head-on with a 1350-kg car traveling with a velocity of 10 m/s due north. the two vehicles stick together after the collision. what is the momentum of each vehicle prior to the collision?

Momentum of Truck

Momentum of car

Explanation:

Given

mass of truck(m)=4000 kg

Velocity of Truck is ()=

mass of car ()=1350 kg

Velocity of car

Conserving momentum

Momentum of Truck

Momentum of car

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
