Physics Acceleration

A baseball player hits a line drive. Just before the ball is struck, it is moving east at a speed of 38.8 m/s (87 mi/h). Just after contact with the bat, 1.05 10-3 s later, the ball is moving west at a speed of 46 m/s (103 mi/h). Find the ball's average acceleration.

  1. Δp=p₂-(-p₁) = p₂ + p₁ = m(v₂+v₁),
    F= Δp/Δt=ma ,
    m(v₂+v₁)/Δt = ma,
    a= (v₂+v₁)/Δt=
    =(46+38)/1.05•10⁻³=8•10⁴ m/s²
