The masses of the blocks, and their velocities before and after collision are given as shown in the figure. Which best describes the given collision? 1.8 m/s 0.2 m/'s 0.6 m/'s 1.4 m/s 4 kg 6 kg 4 kg 6 kg Before After The given collision is not possible because momentum is not conserved. It shows completely inelastic collision. It is characterized by an increase in kinetic energy. It is an example of perfectly elastic collision.0 0 00 nDow An Olympic diver dives off the high-diving platform. The magnitude of his momentum will be maximum at pointIn a certain movie, Superman is at rest in space when he throws an asteroid that has more mass than he does. Which of the following inferences is correct? Cannot be determined. The asteroid will move faster due to greater force exerted by Superman. They will both move at the same speed. Superman will move faster due to small mass.What impulse would be needed to stop a 1600 kg car traveling at 20 m/s? 32 000 kg m/s 16 000 kg m/s -16 000 kg m/s OO -32 000 kg m/sA 4 kg cart, A, is on a horizontal frictionless track and next to a 1 ke cart, B. There is an explosion between the two carts that causes them to go apart. hit this pin to release plunger Which of the following statements is true about the impulse on the 4 kg cart and on the 1 kg cart? The 4 kg cart experiences impulse that is 4 times larger than that of the 1 kg cart The 4 ke cart experiences impulse that is 4 times smaller than that of the 1 kg cart The impulse on the carts can't be determined. The 4 kg cart experiences the same impulse as the 1 kg cart.A rifle recoils from firing a bullet. The speed of the rifle's recoil is small because the: impulse on the rifle is less than the impulse on the bullet. rifle has more mass than the bullet. force against the rifle is relatively small. the momentum of the rifle is unchanged.A block of mass m - 15 kp and speed Vis behind a block of mass M-35 kg and speed of 0.50 m/s, as shown in the figure below. The surface is frictionless and the blocks collide and couple. After the collision, the blocks have a common speed of 0.90 m/s. What is the momentum of the 15 kg block before collision? 0.50 m/'s 0.90 m/'s before after 18 ke m/'s 45.0 kg m/s 32 kg m/s 27 ky m/'sCompared to a sports car moving at 48 km/h, the same sports car moving at 96 km/h has: twice as much momentum. four times as much momentum. the same momentum. half as much momentumWhen we land on the ground from a certain height, we instinctively bend our knees. Which of the following best explain the situation? Bending our knees increases the time for us to stop which increases the force of impact. Bending our knees requires a greater force which lessens the total impulse acting on us Bending our knees extends the time of impact upon landing so that the force on us is decreased. Bending our knees reduces the time of impact so that the force on us will be decreased.A 1500 kg truck traveling at 80 km/h collides with a car of mass 1000 kg traveling at 30 km/h in the same direction. The two cars stick together after the collision. Their speed immediately after the collision is_ 110 km/h 40 km/h 55 km/h 60 km/h
