a 3 kg sphere moving at 30 nvs makes a perfectly inelastic the same mass. (a) find the direction of motion of the cue ball collision with a second sphere that is at rest. the spheres have a after the impact. {b) calculate the speed of each ball after the velocity of 10 mvs after the collision. (a) what is the mass of collision. the second sphere? {b) how much kinetic energy is lost in the collision?

Final answer:

In a physics problem about inelastic collisions, two spheres collide resulting in a shared velocity post-collision, and calculation of kinetic energy lost is required, using the mass of the second sphere being equal to the first (3 kg).

Step-by-step explanation:

The question involves concepts from Physics, particularly dealing with inelastic collisions in one dimension. Given a 3 kg sphere moving and colliding inelastically with another sphere of the same mass at rest, we calculate outcomes such as the common velocity after the collision and the kinetic energy lost.

For part (a), assuming a perfectly inelastic collision, the velocity after the impact for both spheres would be 15 m/s in the initial direction of the moving sphere. For part (b), to calculate the kinetic energy lost, one would use the formula for kinetic energy (KE = 0.5 * m * v^2) before and after the collision.

The mass of the second sphere is given as 3 kg, which is the same as the first one. The kinetic energy lost can be computed using the difference in kinetic energy pre- and post-collision.
