Godzilla is fighting Mothra in Tokyo. Godzilla climbs a tall building and, while standing on the top of the building, Mothra slams into him at a speed of 400  m/s. Godzilla grabs onto Mothra during the impact and they are thrown from the top of the building. If Godzilla has a mass of 9 * 10 3 kg and Mothra has a mass of 3.1 * 10 3 kg, how fast are the two monsters going as they pitch from the top of the building?

Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.65 m/s, and bumper car 2 is traveling 77.7° south of west at 4.10 m/s. They collide and stick together, as the driver of one car reaches out and grabs hold of the other driver. The two bumper cars move off together after the collision, and friction is negligible between the cars and the ground. Car 2 W-OE Car 1 (a) If the masses of bumper cars 1 and 2 are 596 kg and 625 kg respectively, what is the velocity of the bumper cars immediately after the collision? magnitude m/s direction ° east of south (b) What is the kinetic energy lost in the collision?

As you take your leisurely tour through the solar system, you come across a 1.15 kg1.15 kg rock that was ejected from a collision of asteroids. Your spacecraft's momentum detector shows a value of 1.91×108 kg⋅m/s1.91×108 kg⋅m/s for this rock. What is the rock's speed?

What is the momentum in kg · m/s of a garbage truck that is 1.10 ✕ 104 kg and is moving at 34.0 m/s? (Enter a number.)?kg · m/s At what speed in m/s would an 8.00 kg trash can have the same momentum as the truck? (Enter a number.)?m/s
