Question

Examine the image shown here. Bike helmets like this one have padding made of foam under the hard exterior of the plastic. The foam is what is in contact with the head of the wearer. These are safer in an accident than a non-foam padded helmet for which reason? A) The foam increases the inertia. B) The foam increases the momentum. C) The foam increases the time of impact. D) The foam decreases the time of impact.

Answer 1

The foam decreases the time of impact.

What is Impulse?

The Impulse applied to an object causes a change in the momentum of the object. Impulse is the product of force and time of impact.

J = Ft

where;

• J is the impulse
• F is the applied force
• t is the time of impact

The increase in the time of impact increases the impulse experienced by the object, and a decrease in the time of impact causes a decrease in the impulse experienced by the object.

Thus, we can conclude that the foam decreases the time of impact because it cushions the effect of impact.
