Answer:
Option (B).
Step-by-step explanation:
Given that,
Speed of Pam is 50 km/h
Force acting on an object is given by: F = ma
Pam is driving a car, and Dave is riding in the front passenger seat. Both are wearing seatbelts. As Dave's mass is 1.5 times that of Pam. It means that Dave experiences 1.5 times the force that Pam experiences.
Hence, the correct option is (B).
