Two trains (on separate tracks) travel toward each other, the first at 60.0 km/hr and the second at 40.0 km/hr. Both turn on their whistle, the first one emitting a frequency of 200 Hz and the second one emitting a frequency of 220 Hz. What frequencies do they each receive if the speed of sound in air is 330 m/s? Hint: Draw a diagram . Is the source or the observer moving?
An amusement park ride consists of a swing hanging from a chain attached to a spinning mechanism. The swing forms a horizontal circle of a radius 5.0 m and the chain makes an angle of 25 degrees from vertical as shown in the diagram. If the mass of t..
A 2250 kilogram car traveling at 10.0 m/s collides with a car of mass 2750 kilogram that is initially at rest at a stoplight. Obtain coefficient of kinetic friction between cars and road
A spring has a force constant of 100 N/m and an unstretched length of .07 m. One end is attached to a post that is free to rotate in the center of a smooth table.
Suppose a light bulb is rated for a voltage of 1.8 V. At this voltage is draws a current of 0.054A, Using Ohm's Law, determine the resistance of the bulb
Ricardo and Maria both move to the center of the canoe. Ricardo notices that the canoe moves a distance d = 0.37 m relative to a rock that is stationary in the water. What is Maria's mass in kg
At the local grocery store, you push a 14.7-kg shopping cart. You stop for a moment to add a bag of dog food to your cart. With a force of 12.0 N, you now accelerate the cart from rest through a distance of 2.14 m in 3.00 s. What was the mass of the ..
A particle known as a pion lives for a short time before breaking apart into other particles. Suppose a pion is moving at a speed of 0.987c, how far does the laboratory move before the pion breaks apart
Impulse and momentum change/varying force. A 10-kg asteroid is traveling through space at 2 m/s toward a spaceship. To avoid a collision, an astronaut, with the help of a backpack rocket, exerts a force of 20 N on the asteroid in the opposite dire..
