Two objects of the same mass move towards each other at the same constant speed. What can be said of the momentum of each object?

Is the eccentricity of planet orbits closer to 1 or 0?

A 2.0 kilogram rifle initially at rest fires a 0.002 kilogram bullet. As the bullet leaves the rifle with a velocity of 500 meters per second, what is the momentum of the rifle - bullet system?

In a physics lab, a 0.500-kg cart (Cart A) moving with a speed of 129 cm/s encounters a magnetic collision with a 1.50-kg cart (Cart B) that is initially at rest. The 0.500-kg cart rebounds with a speed of 45 cm/s in the opposite direction.

Tell me awesome facts about light.

Different structural forms of the same element are called

A mechanic pushes a 3.60 ✕ 103-kg car from rest to a speed of v, doing 5,130 j of work in the process. during this time, the car moves 21.0 m. neglecting friction between car and road, find v and the horizontal force exerted on the car.

Anika asks Eva to roll a basketball and then a bowling ball to her. Which requires more force to roll, and why?

Why does a buoyant force act on every object in a fluid? Pressure pushing up on the bottom of the object is greater than the pressure pushing down on the top.

Give a sentence with the word velocity in it
