10. [1/2 Points] DETAILS An object is traveling such that it has a momentum of magnitude 26.9 kg m/s and a kinetic energy of 232 J. Determine the following. (a) speed of the object in meters per second 26.9 x Expressions for both the kinetic energy and momentum of an object involve mass and speed. See if you can start with expressions for the kinetic energy and momentum, eliminate the mass, and determine an expression in terms of the kinetic energy and momentum that will allow you to determine the speed. m/s (b) mass of the object in kilograms 1.56 ✓kg Additional Materials Reading PREVIOUS ANSWERS OSCOLPHYS2016 8.1.WA.005. DETAILS 11. [0/1 Points] A member of the volleyball team spikes the ball. During this process, she changes the velocity of the ball from 2.7 m/s to -23.0 m/s along a certain direction. If the impulse she delivers to the ball is -7.0 kg. m/s, determine the mass of the volleyball in kilograms. 0.28 Additional Materials Reading PREVIOUS ANSWERS X Knowing the impulse and the initial and final velocity of the ball, you can determine the mass of the ball. kg OSCOLPHYS2016 8.2.WA.007.
