Two particles with the same mass of 11 kg are involved in a completely inelastic head-on collision. Before the collision both particles have the same speed of 3 m/s. Which statement below describes the velocities of the particles after the collision? One of the particles continues at 3 m/s, and the other reverses direction and moves at 6 m/s. Each particle's speed is still 3 m/s, but each has reversed its direction. There is not enough information to determine the velocities after the collision. One of the particles continues to move at 3 m/s, while the other particle is at rest. Both particles have zero velocity.

How do you tell if someone actually cares about you? and just say they do?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
