Final answer:
The magnitude of the net force on the door during the collision with a potato is not directly related to the weight of the dart.
Step-by-step explanation:
The magnitude of the net force on the door before, during, and after the collision with a potato can be described by the equation Fnet = m(dv/dt), where Fnet is the net force, m is the mass of the door, and (dv/dt) is the rate of change of velocity. The weight of the dart, represented by W, is not directly related to the net force on the door during the collision. Therefore, the claims (d) 1.76 × 10³ N or 3.00 W and (e) the normal force (upward) is three times her weight are not valid in describing the magnitude of the net force on the door during the collision.
