## Question:

In Example 8.1, the mosquito has an inertia of $$0.1 \mathrm{~g}$$ and is initially at rest, while the bus, with an inertia of $$10,000 \mathrm{~kg}$$, has an initial speed of $$25 \mathrm{~m} / \mathrm{s}$$. The collision lasts $$5 \mathrm{~ms}$$.

(a) Calculate the final speeds of the mosquito and the bus.

(b) What is the average acceleration of each during the collision?

(c) By how much does the momentum of each change?

(d) During the collision, how large is the average force exerted by the bus on the mosquito?

(e) How large is the average force exerted by the mosquito on the bus?

Data from Example 8.1

A mosquito splatters onto the windshield of a moving bus and sticks to the glass.

During the collision, is the magnitude of the change in the mosquito's momentum smaller than, larger than, or equal to the magnitude of the change in the bus's momentum?

During the collision, is the magnitude of the average force exerted by the bus on the mosquito smaller than, larger than, or equal to the magnitude of the average force exerted by the mosquito on the bus?
