1. what is the kinetic energy of a 65 kg rocket traveling at 109 m/s? ( j ) type answer as a whole number (no decimals). type the number only, not the units. use commas: for example, type 100,000, not 100000 2. what is the momentum of the rocket in the previous problem? ( kg · m/s) type answer as a whole number (no decimals, no commas). type the number only, not the units.
