Homework Statement
If a ball strikes a surface with an input velocity of 18m/s, incident angle 25 degrees, mass = 2.5kg, Coefficient of restitution 0.8 and Coefficient of friction 0.6 how would you calculate the output velocity and angle? I can work it out with restitution only but how do you factor in friction?
Homework Equations
The Attempt at a Solution
Without frictionhorizontal
2.5x18cos 25 = 2.5 x Vcosσ
Vcosσ = 16.3
Vertical
-Vsinσ = -CoR(18sin25)
Vsinσ = 6.09
Relating V and σ gives
σ=20.5 degrees
V=17.4m/s
