PLEASE HELPPP Ball A of mass 5.0 kg moves at a speed of 4 m/s. It collides with a second stationary ball B, also
of mass 5.0 kg. After the collision, ball A moves off in the direction 45 degrees to the left of its
original direction. Ball B moves off in the direction 45 degrees to the right of ball A's original
direction.
a. Draw a vector diagram to determine the momentum of ball A and ball B after the collision.
b. What is the speed of each ball after the collision?

1. when conducting a test on what kind of music increases the growth of plants, all of the following would fail to meet to fair test standard except (1 point) using different kinds of plants. giving some plants more water than others. exposing the plants to different types of music. using nutrient-rich soil for one and lesser soil for others. 2. engineering uses scientific thinking to solve real-world problems. (1 point) true false 3. what does it mean to test a hypothesis? (1 point) pass a quiz on other scientists’ results analyze only the results from scientific sources not make assumptions about how an experiment will turn out see if the results of an experiment are what the scientist predicted
