Answer:

  • the coefficient of restitution is 0.8.

Given that

  • A ball hits a wall going 10 m/s, and bounces off going 8 m/s.

To find

  • the coefficient of restitution

So according the question

We have

  • The initial velocity of approach towards the wall is  

                       u = 10 m/s.

  • The final velocity of separation from the wall after the collision is  

                      v = 7 m/s.

Now, We have to find the coefficient of restitution

We know that,

         [tex]n = \frac{velocity \;\;of \; \;separation}{velocity \;of \;approach}[/tex]

So,

             [tex]n = \frac{8}{10}[/tex]

              n = 0.8

Answer:

  • The coefficient of restitution is 0.8.
