A particle moving on a smooth horizontal surface strikes a stationary wall. The angle of strike is equal to the angle of rebound & is equal to 37° and the coefficient of restitution with wall is e = 1/5. Find the friction coefficient between wall and the particle in the form X/10 and fill value of X.:
Since e = 1/5
∴ Final normal component of velocity = vcos37°/5.
As the angle of rebound is equal to the angle before impact.
Therefore, both normal & tangential components of velocities must change by the same factor.
