Two objects with different masses have the same momentum. The less massive object will have a greater kinetic energy. True or False

When the mass of an object moving at a constant speed doubles, its momentum changes by a factor of _______, and its kinetic energy changes by a factor of _______.

There is a large crater in Arizona called Meteor Crater. It is estimated that it was formed about 20,000 years ago by a meteorite that had a mass of about 5 x 10^10 kg and was traveling at a speed of 7.5 km/sec. How fast could this meteorite have hit the Earth (whose mass is 6 x 10^24 kg) if we assume a head-on collision?

Hi, can you please give me a solution why the answer to this question is 6 m/s? Thanks.    When a light beach ball rolling with a speed of 6.0 m/s collides with a heavy exercise ball at rest, the beach ball's speed after the collision will be, approximately Answer: 6m/s

Two balls are about to collide. Ball 1 has a mass of 10kg, and is moving [down] at an unknown speed. Ball 2 is 11kg and is moving [up] at a speed of 6m/s. After they collide, ball 1 moves with a velocity of 8m/s [60° Up of right]. Ball 2 moves with an unknown velocity [55° down of left]. An image has been added to help picture the situation. What is the initial velocity of ball 1? 260° 59 5.1m/s [down] 5.38m/s [down] O 6.34m/s [down] O 6.9m/s [down]

A VW beetle going 80 km/hr East, hits a Mack truck, 10 times the mass of the beetle, head on, going 60 km/hr West. They fuse into one mass. At what speed will they move off together?  In what direction? Will energy be conserved?
