Respuesta :
a) since force = mass * acceleration
f= 900 * 0 (because constant speed = 0 acceleration)
similarly b) f = 0
Answer:
The car travels at twice the velocity of the truck.
Explanation:
As we know that momentum is defined as the product of mass and velocity
so here we know
mass of the car = 900 kg
mass of the truck = 1800 kg
now let say that the speed of car = [tex]v_1[/tex]
speed of truck = [tex]v_2[/tex]
so if the momentum of car and truck is same
[tex]900 v_1 = 1800 v_2[/tex]
[tex]v_1 = 2 v_2[/tex]
so we can say that car will move with double the speed of truck
