At one instant, the center of mass of a system of two particles is located on the x-axis at and has a velocity of . one of the particles is at the origin. the other particle has a mass of 0.10 kg and is at rest on the x-axis at (a) what is the mass of the particle at the origin? (b) calculate the total momentum of t

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

If two students are running down the hall toward each other, trying to get to class, and they have the same mass and acceleration, what will happen when they collide? will their forces cancel out or will each one experience a reaction?
