Mechanics: Momentum and Collisions Momentum and Collisions:
Audio Guided Solution A 92-kg fullback moving south with a speed
of 5.8 m/s is tackled by a 110-kg lineman running west with a
speed of 3.6 m/s. Assuming momentum conservation, determine the
speed and direction of the two players immediately after the
tackle. Audio Guided Solution Click to show or hide the answer!
3.3 m/s, 53° S of W Habits of an Effective Problem Solver - Read
the problem carefully and develop a mental picture of the
physical situation. If necessary, sketch a simple diagram of the
physical situation to help you visualize it. - Identify the
known and unknown quantities in an organized manner. Equate
given values to the symbols used to represent the corresponding
quantity - e.g., m = 1.50 kg, vi = 2.68 m/s, F = 4.98 N, t =
0.133 s, vf = ???. - Use physics formulas and conceptual
reasoning to plot a strategy for solving for the unknown
quantity. - Identify the appropriate formula(s) to use. -
