![]() Determine the momentum of the airplane at takeoff.Į. Complete a conservation of momentum diagram showing how the initially stationary airplane gets to takeoff speed. Determine the time the plane takes to go from 0 to 170 mph. (Data from Boeing's website.) Takeoff speed depends on a number of factors like air temperature, airplane weight, and airport elevation, but let us say that liftoff will occur at 170 mph. A fully loaded, 396,900 kg Boeing 747-400 gets a total of 1100 kiloNewtons of thrust from its jet engines. Airplanes maneuver on the ground by using thrust from their jets or propellers. Complete a qualitative conservation of momentum diagram where the apple is initially attached to the tree and the final situation is just before the apple hits the ground. How many times larger will the final velocity of the alpha particle be compared to the final velocity of the radon-222?Ĥ. ![]() (Recall from chemistry that the isotopic number of an element is related to its mass.) event: initial object/mass/velocityĬ. Complete a qualitative momentum conservation diagram for the radioactive decay of radium-226. ![]() When radium-226 decays, it becomes radon-222 by ejecting an alpha particle - two protons and two neutrons (a helium nucleus). Complete the momentum conservation diagram for the accident. On an icy road, a 5000 kg truck rear-ends a 1200 kg car that had been traveling at 13 m/s, causing the truck to slow from 14 m/s to 12 m/s and the car to speed up. Complete a conservation of momentum diagram for firing one of these cannons. When a 150 kg cannon and cart recoils at 1.5 m/s, at what velocity would a 10.0 kg cannonball leave the cannon? a. ![]() Old cannons were built on wheeled carts, both to facilitate moving the cannon and to allow the cannon to recoil when fired. ![]()
