Might be 20 kg-m/s
The total momentum before the collision is 10,000 kg m/s (1000 kg * 10 m/s) in the direction of Car 2's initial velocity. Since the system is isolated, momentum is conserved. After the collision, the total momentum is still 10,000 kg m/s, but now shared between the two cars.
Yes, gravity acts on a moving bicycle. Gravity pulls the bicycle and the rider toward the center of the Earth, influencing their motion. This force helps to keep the bicycle in contact with the ground and affects its acceleration and speed.

The magnitude of the upward acceleration of the load of bricks is the measure of how fast the load is moving upwards.
Yes, two cars moving with the same velocity can collide if their paths intersect or if one fails to stop in time to avoid hitting the other. Velocity only describes the speed and direction of an object's motion, not its position. So, the cars can still collide if they have the same velocity.
20 kg-m/s
In an isolated system, momentum is conserved. The total initial momentum is the sum of the momentum of Bicycle 1 and the momentum of Bicycle 2. Given the masses and velocities of the bicycles, you can calculate their momenta and add them together to find the total initial momentum of the system.

The momentum of an object is given by the product of its mass and velocity. The momentum of bike 1 is 30 kg x 2 m/s = 60 kg.m/s to the right, and the momentum of bike 2 is 30 kg x 4 m/s = 120 kg.m/s to the left. When bike 1 and bike 2 collide in an isolated system, the total momentum is conserved. The magnitude of their total momentum is 60 kg.m/s + 120 kg.m/s = 180 kg.m/s.
10,000 kg-m/s
You are not moving relative to the bicycle.
The "C" stands for "Collider" For something to collide there has to be a second something moving in a different direction to collide with. The contents of the two beams moving in opposite directions collide.
the magnitude is 43.3 and the direction is upward.
