Electrons are accelerated to high speeds by a two-stage machine. The first stage accelerates the electrons from rest to 0.99 c, and the second stage accelerates the electrons from 0.99 c to 0.999 c. By how much does each stage increase the kinetic energy of an electron?
1. A rocket accelerates upward from rest during the first stage with a constant acceleration of a1 = 95.0 m/s2 for t1 = 30.0 s. The first stage then detaches and the second stage fires, providing a constant acceleration of a2 = 50.0 m/s2 for t2 = 60.0 s. (a) What is the total distance traveled by the rocket during both stages? (b) What is the speed of the rocket after the second stage burn?
Calculate the final speed (in m/s) of an alpha particle (two protons, two electrons) accelerated from rest through a potential difference of 98.4 V. (Note: thanks to binding energy, the actual mass of an alpha particle is 6.645
-31 1 Electrons have a rest mass of 9.1095x103"kg(0.511 MeV/c2) and an energy of 0.511 MeV million electron volts) when at rest. In a colliding beam experiment, a beam of electrons accelerated to a high speed is sent toward a beam of antielectrons (same mass as electrons) moving in the opposite direction at the same speed. a.) Experimenters hope to create the J/y particle that has a rest mass energy of 3097 MeV through one of these collisions. The J/y...
In a cathode ray tube, electrons are accelerated from rest by a constant electric force of magnitude 6.40 × 10−17 N during the first 2.60 cm of the tube’s length; then they move at essentially constant velocity another 45.0 cm before hitting the screen. (a)Find the speed of the electrons when they hit the screen. ___m/s (b)How long does it take them to travel the length of the tube? ___ns
1. An automobile starts from rest and accelerates to a final velocity in two stages along a straight road. Each stage occupies the same amount of time. In stage 1, the magnitude of the car's acceleration is 2.99 m/s2. The magnitude of the car's velocity at the end of stage 2 is 2.20 times greater than it is at the end of stage 1. Calculate the magnitude of the acceleration in stage 2. 2. The Space Shuttle travels at a...
A process has two stages. In the first stage, a machine makes two components, call them type A and B. It takes 250 seconds to switch production between the component types. During that time no production occurs. When in production, each component (A or B) requires 0.6 seconds to be completed. In the second stage, the components, A and B, are assembled to make a final product, call it C. The assembly stage can combine the two components into 1...
5. Starting from rest, a particle confined to move along a straight line is accelerated at a rate of 5.0 m/s Which one of the following statements accurately describes the motion of this particle? A) The particle travels 5.0 m during each second. B) The particle travels 5.0 m only during the first second. C) The speed of the particle increases by 5.0 m/s during each second. D) The acceleration of the particle increases by 5.0 m/s during each second....
2. A cyclotron is a device used to accelerate charged particles to high speeds. It consists of two hollow containers -called dees because of their shape facing each other and separated by a small gap. They are immersed in a uniform magnetic field, B, and are attached to a source of alternating voltage. A charged particle is projected from the center of the cyclotron into Dee #1, and the magnetic force causes it to turn in a cirele. When it...
A certain merry go round is accelerated uniformly from rest and attains an angular speed of 1.2 rad/s in the first 18 seconds. Also given (if needed): Net applied torque is 1200 Nm Moment of inertia is 18181 kg•m^2 Kinetic Energy is 13090 J Assuming friction is negligible, how much work does the motor have to do to accelerate the merry go round up to 1.2 rad/s? How much power does the motor have to generate to accelerate the merry...
