What is the momentum of a 3 kg bowling ball moving at 3 m/s?1 kg • m/s3 kg • m/s6 kg • m/s9 kg • m/s
Which sea creature has the most momentum? [___]
Consider a system to be one train car moving toward another train car at rest. When the train cars collide, the two cars stick together.What is the total momentum of the system after the collision?800 kg • m/s1,600 kg • m/s2,400 kg • m/s4,000 kg • m/s
Two balls, each with a mass of 0.5 kg, collide on a pool table. Is the law of conservation of momentum satisfied in this collision? Explain why or why not.
Yes, the law of conservation of momentum is satisfied in this collision. The total momentum of the system before the collision is equal to the total momentum of the system after the collision, assuming no external forces act on the balls.
Train car A is at rest when it is hit by train car B. The two cars, which have the same mass, are stuck together and move off after the collision. How does the final velocity of train cars A and B after the collision compare to the initial velocity of train car B before the collision?The final velocity is double train car B’s initial velocity.The final velocity is the same as train car B’s initial velocity.The final velocity is half of train car B’s initial velocity.The final velocity is zero si
