1. A rocket launched by Space-Y has mass 2.0 x 10 kg before it explodes. If its speed just as it
explodes is 1.8 x 10 m/s, what is its momentum magnitude?
2. Find the speed of a particle if its kinetic energy is 275 J and its momentum has magnitude 25.0 kg
m/s
BONUS: What is the mass of the particle?
3. During an instant in time, a particle's momentum is 31 kg. m/s and its speed is 9.0 m/s. At the
same time, its total mechanical energy is 230 J. What is the particle's elevation from the ground?
Use 3 significant figures in your final answer. Use as many decimal places in between
calculations as possible for your answer to be accurate.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F150ad1c2-64bd-4f4a-b809-6a730a073d41%2F3a7517b9-3661-4b97-942b-e9a124522d06%2Fbzgxgmq_processed.png&w=3840&q=75)
