Question

which of newtons laws explains why a test dummy continues forward until it makes contact with another object? newtons first law newtons second law newtons third law

Explanation:

Newton's first law (law of inertia) states that an object in motion stays in motion with constant velocity unless acted upon by an unbalanced external force. The test dummy continues moving forward until another object (external force) stops it, which matches this law. Newton's second law relates to force, mass, and acceleration, while the third law describes action-reaction pairs, neither of which apply here.

Answer:

Newton's first law
