Two objects have the same momentum. Do they necessarily have the same kinetic energy? Explain.
Answer to relevant QuestionsTwo objects have the same kinetic energy. Do they necessarily have the same momentum? Explain. An airboat of the type used in swampy and marshy areas is shown in Fig. 6.29. Explain the principle of its propulsion. Using the concept of conservation of linear momentum, determine what would happen to the boat if a sail ...In football practice, two wide receivers run different pass receiving patterns. One with a mass of 80.0 kg runs at 45o northeast at a speed of 5.00 m/s. The second receiver (mass of 90.0 kg) runs straight down the field (due ...For the karate chop in Fig. 6.27, assume that the hand has a mass of 0.35 kg and that the speeds of the hand just before and just after hitting the board are and 0, respectively. What is the average force exerted by the fist ...A 50-kg driver sits in her car waiting for the traffic light to change. Another car hits her from behind in a head-on, rear-end collision and her car suddenly receives an acceleration of 16 m/s2. If all of this takes place ...
