In Example 8.1, the mosquito has an inertia of 0.1 g and is initially at rest, while the bus, with an inertia of 10,000 kg, has an initial speed of 25 m/s. The collision lasts 5 m/s. (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?

A typical raindrop is much more massive than a mosquito and falls much faster than a mosquito flies. How does a mosquito survive the impact? Recent research has found that the collision of a failing raindrop with a mosquito is a perfectly inelastic collision. That is, the mosquito is "swept up" by the raindrop and ends up traveling along with the raindrop. Once the relative speed between the mosquito and the raindrop is zero, the mosquito is able to detach...

Two blocks have masses mi = 5 kg and m2 = 1 kg and speeds v1 = 2 m/s and v2 = 5 m/s. The objects slide directly toward each other along a frictionless horizontal surface and collide. After the collision, block mi is at rest. (Hint: impulse, linear momentum conservation) a. What is the magnitude of the impulse, Jil, exerted on block mı during the collision? b.

Use the worked example above to help you solve this problem. In a crash test, a car of mass 1.44 103 kg collides with a wall and rebounds as shown in the figure. The initial and final velocities of the car are vi = -15.2 m/s and vf = 2.11 m/s, respectively. If the collision lasts for 0.153 s, find the following. (a) the impulse delivered to the car due to the collision kg · m/s (b) the size of...

Part A Problem 9.62 A hovering mosquito is hit by a raindrop that is 30 times as massive and falling at 8.9 m/s, a typical raindrop speed. How fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic? A typical raindrop is much more massive than a mosquito and falling much faster than a mosquito flies. How does a mos quito survive the impact? Recent research has found that the collision of a...

Mass m = 0.1 kg moves to the right with speed v = 0.52 m/s and collides with an equal mass initially at rest. After this inelastic collision the system retains a fraction=0.77 of its original kinetic energy. If the masses remain in contact for 0.01 secs while colliding, what is the magnitude of the average force in N between the masses during the collision? Hints: All motion is in 1D. Ignore friction between the masses and the horizontal surface....

A 200 g meter stick has a 50.0 g lump of clay stuck on it at the 10.0 cm mark. It is initially at rest on a level, frictionaless surface, lying along the y-axis with its 50.0 cm mark at the origin. A second 50.0 g lump of clay, initially moving at 1.20 m/s i, collides with the meter stick and sticks to it at the 90.0 cm mark. 1. What is the initial momentum of the system of the...

A 0.230 kg billiard ball that is moving at 5.00 m/s strikes the bumper of a pool table and bounces straight back at 4.00 m/s (80% of its original speed). The collision lasts 0.0220 s. (Assume that the ball moves in the positive direction initially.) (a) Calculate the average force (in N) exerted on the ball by the bumper. (Indicate the direction with the sign of your answer) (b) How much kinetic energy in joules is lost during the collision?...
