Question

Use calculation to show whether the collision is elastic or inelastic​

Answer 1

Answer:

inelastisc Or elastic whatever may be one of those answers

Answer 2

→  First of all, calculate velocity of separation:

28-(-20) = 48 m/s

→  Now, calculate velocity of approach

30-(-25) = 55 m/s

We know that;

coefficient of restitutuion (e) =  (velocity of separation)/(velocity of approach)

                                             → e = 48/55

∵ value of coefficient of restitutuion (e) is in between 0 and 1.

∴ the collision is inelastic collision.

EXTRA INFORMATION:

Whether the collision is elastic or inelastic, doesn't depend on the masses of the bodies.
