EXAMPLE 4 A solid ball with a mass m is thrown on the ground such that at the instant of contact it has an angular velocity and velocity components (VG) and (VG) as shown. If the ground is rough so no slipping occurs, determine the components of the velocity of its mass center just after impact. The coefficient of restitution is e. (va)yt (va)a
The figure shows n spheres of equal mass m suspended in a line by wires of equal length so that the spheres are almost touching each other. If sphere 1 is released from the dashed position and strikes sphere 2 with a velocity v₁, write an expression for the velocity Vn of the nth sphere immediately after being struck by the one adjacent to it. The common coefficient of restitution is e. What is the velocity of sphere 21 immediately after being struck by sphere 20 if v₁ = 4.2 m/s and e = 0.67? AIL Answer: V21 = i th m/s
