Physics

A speeder passes a parked police car at a
constant speed of 23.9 m/s. At that instant,
the police car starts from rest with a uniform
acceleration of 2.21 m/s
2
.
How much time passes before the speeder
is overtaken by the police car?
Answer in units of s

How far does the speeder travel before being
overtaken by the police car?
Answer in units of m

  1. X1 = 23.9 t
    X2 = 1,105 t^2

    Set X1 = X2 and solve for t

    Then use that t and either equation for the location where they meet.
