Urgent! what makes some collisions elastic and and other inelastic? a. if the collision involves bouncing, it is elastic. b. if the collision involves sticking together, it is elastic. c. if there is no loss of kinetic energy, it is elastic. d. if there is energy lost in the collision to sound, heat, etc., the collision is elastic.

look at me answering a question from 2017 its 2021 \(^o^\) (/^o^)/

C is correct tho I just took the test '^'

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

cancer risk hope this
