The total momentum should come out to be  <span>2.0 x 10^4 kilogram meters/second </span>

Answer:

Momentum in X direction = 20400 kg m/s

Explanation:

As we know that there is no external force on this system of two cars

so here the momentum of two cars will remains conserved always

So here we can say that initial total momentum of two cars in Y direction is given as

P_y = mv_y

P_y = 998 (20) = 19960 kg m/s

Now for X direction total momentum is given as

P_x = mv_x

P_x = 1200(17) = 20400 kg m/s

so here its momentum in x direction will always remains the same and its final momentum in x direction is given as

P_x = 20400 kg m/s

Allisa [31]

Answer:

the net force applied to the car is zero.

Explanation:

According to Newton's second law, the acceleration of an object (a) is directly proportional to the net force applied (F):

a=\frac{F}{m}

where m is the object's mass.

In this problem, the car is moving with constant velocity: this means that the acceleration is zero, a = 0. Therefore, according to the previous equation, the net force must also be zero: F = 0. So, the correct answer is

the net force applied to the car is zero.
