When a 1.0-kilogram cart moving with a speed of
0.50 meter per second on a horizontal surface
collides with a second 1.0-kilogram cart initially
at rest, the carts lock together. what is the speed
of the combined carts after the collision?
[neglect friction.]
(1) 1.0 m/s (3) 0.25 m/s
(2) 0.50 m/s (4) 0 m/s

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

Which describes increasing the efficiency of energy resource

An ascending elevator, hanging from a cable, is coming to a stop. part a part complete identify all forces acting on the elevator from the list below. select all that apply. select all that apply. kinetic friction normal force tension weight static friction submitprevious answers correct part b draw a free-body diagram of the object. draw the vectors starting at the black dot. the location and orientation of the vectors will be graded. the exact length of your vectors will not be graded but the relative length of one to the other will be graded.
