How does the force of impact during a collision change when the time of contact is reduced?(1 point)

a. It decreases.

b. It increases.

c. It remains the same.

d. It instantaneously becomes zero.

b. It increases.

The force of impact during a collision can be calculated using the equation: F = (m * Δv) / Δt, where F is the force, m is the mass of the object, Δv is the change in velocity, and Δt is the time of contact.

When the time of contact is reduced, Δt becomes smaller. As a result, if the change in velocity, Δv, stays the same, the force of impact, F, will increase because the denominator of the equation becomes smaller. This means that the force of impact becomes greater when the time of contact is reduced.

Therefore, the correct answer is b. It increases.
