A kicking-simulation attachment goes on the front of a wheelchair, allowing athletes with mobility impairments to play soccer. The athletes load up the spring shown through a ratchet mechanism that pulls the 2.45-kg "foot" back to the position 1. They then release the "foot" to impact the 0.45-kg soccer ball that is rolling towards the "foot" with a speed of 5 m/s at an angle 0 = 30° as shown. The impact occurs with a coefficient of restitution e = 0.75 when the foot is at position 2, where the spring is unstretched. The effective friction coefficient during rolling is μK = 0.1.
