The following questions refer to a situation in which you are riding in a car that crashes into a solid wall. The car comes to a complete stop without bouncing back. The car has a mass of 1500 kg and has a speed of 30 m/s before the crash (this is about 65 mi/hr). Do this problem on graph paper (click here for printable graph paper) a) What is the car's initial momentum? b) What is your initial momentum? (Recall that the weight of one kilogram is 2.2 lbs) c) Draw separate Momentum Charts for the car and the person. Treat both as open systems with a net impulse. d) What is the change in the momentum of the car? e) What is the change in your momentum?

Step 1
Given: Mass of the car, m = 1500 kg Velocity of the car, v = 30 m/s Using the formula for momentum, p = m * v, we can calculate the initial momentum of the car: Initial momentum of the car = 1500 kg * 30 m/s = 45000 kg m/s Show more…

1. A compact car, mass 725 kg, is moving at 1.00 x 10^2 km/h toward the east. Sketch the moving car. a. Find the magnitude and direction of its momentum. Draw an arrow on your picture showing the momentum. b. A second car, mass 2175 kg, has the same momentum. What is its velocity? 2. The driver of the compact car suddenly applies the brakes hard for 2.0 s. As a result, an average force of 5.0 x 10^3 N is exerted on the car to slow it. Sketch the situation. a. What is the change in momentum, that is the magnitude and direction of the impulse, on the car? b. Complete the "before" and "after" diagrams, and determine the new momentum of the car. c. What is the velocity of the car now? 3. A 7.0-kg bowling ball is rolling down the alley with a velocity of 2.0 m/s. For each impulse, a and b, as shown in Figure 9-3, find the resulting speed and direction of motion of the bowling ball.

1) A 800 kg car has a momentum of 12,000 kg m/s when it has a negative impulse 10,000 kg m/s over 2 seconds. What is the acceleration (in m/s/s) of the car? 2). A 800 kg car has a momentum of 12,000 kg m/s when it has a negative impulse 10,000 kg m/s over 2 seconds. What is the Net Force (in N) acting on the car? 3) A .4 kg ball is moving at +20 m/s when it bounces off the wall and moves backwards at -16 m/s. What is the initial and final momentum (in kg m/s) of the ball? Include + and - signs with your answers.

Suppose a 60.0 -kg person was in the vehicle that hit the concrete wall in Example Problem 1. The velocity of the person equals that of the car both before and after the crash, and the velocity changes in 0.20 s. Sketch the problem. a. What is the average force exerted on the person? b. Some people think that they can stop their bodies from lurching forward in a vehicle that is suddenly braking by putting their hands on the dashboard. Find the mass of an object that has a weight equal to the force you just calculated. Could you lift such a mass? Are you strong enough to stop your body with your arms?
