Friction is a very clever forceClassical Mechanics Level 5
A particle moving on a smooth horizontal surface strikes a stationary wall. The angle of strike is equal to angle of rebound and is equal to 37 degrees.
The coefficient of restitution with the wall is
If the friction coefficient between the wall and the particle is in the form of \(X/10\). Find the sum of the first three multiples of \(X\)
