The combined momentum of the passengers is 5000 kgm/s.
<h3>Combined momentum of the passenger</h3>
The combined momentum of the passengers is calculated as follows;
P = mv1 + mv2
where;
- m is mass of the passengers
- v1 is velocity of the first passenger
- v2 is velocity of the second passenger
P = m(v1 + v2)
P = 5000(-1 + 2)
P = 5000 kgm/s
Thus, the combined momentum of the passengers is 5000 kgm/s.

The acceleration of the bike is equal to opposing the movement (to the right).
Why?
Since after the rider slams the brakes, the bike came to a stop, we know that the acceleration is opposite to the velocity/movement.
We can use the following equation to calculate the acceleration:
So, substituting, we have: (let's consider negative to the left and positive to the right)
The negative sign means that the acceleration's direction is opposite to the movement.
Hence, we have that the acceleration is equal to opposing the movement (to the right).
Have a nice day!
<span>C. The net force is perpendicular to the motion.
When you swing a yo-yo in a circle around your head, the net force
is the tension in the string, pointing toward the center of the circle.
There's nothing there that provides any force parallel or opposite to
the motion.
When the Earth revolves around the Sun in a circular orbit, the net force
is the gravitational force between the Sun and the Earth. There's nothing
</span>there that provides any force parallel or opposite to the motion.
When a system looses heat it is considered exothermic and vice-versa endothermic. But something that is considered cold to us can loose heat and become colder. It is therefore necessary to use a specific temperature when referring to the change.
Answer: They create antibodies.
