Question

what force will the seat belt have to exert on the dummy in item 3 to hold the dummy in the seat

Answer 1

Answer:

Explanation:

The same magnitude as the net force in

item 3 but in the opposite direction..

Answer 2

The force is equal to 450 newton

• When two forces are applied to a dummy simultaneously, one force known as the resultant force can substitute for the combined action of the two forces.
• The vector sum of the two contributing forces is the resulting force. A force that is equal in strength to the net force and acts in the opposite direction should be used to hold the seat in place.

• So, let us say that this is the dummy and that this is the forward and side words, respectively, which is the y direction.
• And X direction is the follower direction. We have a force of 130 newtons moving forward and a force of 4500 newtons moving sideways.
• The magnitude of the resulting force will therefore be 4500^2 +130^2. It was either 4501450 or 4501.877 newtons.
• To the nearest 450. If this is the resulting direction's angle theta, the angle theta is equal to an arc tangent of 4500 over 130.
• Thus, that equals 88 degrees or 88.34 degrees.

• The resulting force, which acts at an angle of 88 degrees to the side when measured from the forward direction, has a magnitude equal to 450 Newton.
