An atomic nucleus initially moving at 375 m/s emits an alpha particle in the direction of its velocity, and the remaining nucleus slows to 250 m/s .
If the alpha particle has a mass of 4.0 u and the original nucleus has a mass of 222 u, what speed does the alpha particle have when it is emitted?
An astronaut comes loose while outside the spacecraft and finds himself floating away from the spacecraft with only a big bag of
tools. In desperation, the astronaut throws his bag of tools in the direction of his motion (away from the space station). The
astronaut has a mass of 102 kg and the bag of tools has a mass of 10.0 kg. If the astronaut is moving away from the space station
at 1.80 m/s initially, what is the minimum final speed of the bag of tools (with respect to the space station) that will keep the
astronaut from drifting away forever?
minimum final speed:
m/s
A 2,950 kg truck jumps the median and clobbers a 660 kg station wagon in a head-on collision. You are tasked with determining the truck’s initial speed for insurance purposes. An observer states that the station wagon was traveling at a speed of 32.5 m/s and that after the collision, the two vehicles stuck together and were moving at a speed of 22.7 m/s in the direction the truck was originally moving. What was the truck’s original speed?
