- Find T in micro second?Should be solved using classical mechanics( Kinematics) Many physicists rely on data from particle accelerators for their research. Consider an alpha particle (the nucleus of a helium atom) traveling inside a straight tube 2.0 m long that forms part of a particle accelerator. The alpha particle enters the tube moving at a velocity 9.5 × 105 m/s and emerges from the other end after 8.0 × 10−7 seconds. (a) If the particle’s acceleration is constant, what is its velocity when it leaves the tube? (b) If instead the particle’s acceleration increases linearly with time as a(t) = kt, where k = 1 × 1019 m/s3, what is its velocity when it leaves the tube? (c) Plot the velocity versus time graph for the alpha particle in parts (a) and (b), for the duration of its travel in the tube.Consider a particle of mass m acted on by a force F in an inertial frame. Prove that dK = F. dr, (1) where dr is the change in the position vector of the particle in a time dt, and dK is the corresponding change in the kinetic energy K = }mv².
- F The force F = 460 N acts on the frame. Resolve this force into components acting along members AB and AC, and determine the magnitude of each component. Given that a = 34° and ß = 47°, The magnitude along AB is (round to one decimal place): The magnitude along AC is (round to one decimal place): NA man of mass 80 kg is standing stationary in the middle of a train carriage (see the figure below). The train is moving horizontally with a constant speed of 20 m/s (see the figure below), and the carriage is L=20 m long. Suddenly, the train starts to accelerate uniformly with a=2 m/s2 horizontally. a) Is the reference frame of the train now an inertial frame? Design an experiment that allows you to find out. b) Draw a free-body diagram of the man. Label the forces appropriately and explain their physical origin (one line each will suffice). c) If the coefficient of friction between the man's shoes and the `floor' of the train is μ=0.1, what is the maximum time that the man takes to hit the back of the train carriage? For simplicity, you can assume that the coefficient of static friction is the same as the coefficient of kinetic friction. Assume that there are no obstacles between the man and the back of the train. d) How does your answer change if the coefficient of…How much time does it take for a mass traveling down a frictionelss slope of 30 degrees of unknown distance to reach a speed of 2.5 m/s. Speed initial = o Slope of infinite length.
- A flexible rope of length L and mass per unit length u slides over the edge of a frictionless table. Initially let a length yo of it be hanging at rest over the edge and at time t let a length y moving with a velocity dy/dt be over the edge. Obtain the equation of motion and discuss its solution.R3B2. Alicia is a student on a passenger train moving at a constant velocity relative to the ground. She synchronizes her watch with the station clock as she passes through the town of Bannon station, and then compares her watch with the station clock as she passes through the Center town station farther down the line. The ground is an inertial frame, and the Bannon and Center clocks are synchronized in that frame. (1) Using a model or diagram, is the time she measures between the events of passing through these towns a proper time? (2) Is it a coordinate time in some inertial reference frame? (3) Is it the spacetime interval between the events?Imagine that you are going for a ride in a hot air balloon at the Canowindra Balloon Challenge. While the balloon is rising at a speed of 2.0 m/s, you throw a small ball down at a speed of 5.0 m/s relative to your body. A person who measures the ball's velocity at the instant of release will find that the ball's velocity relative to the ground at that instant is O a. 3.0 m/s, up. O b. 2.0 m/s, up. O c. 3.0 m/s, down. O d. 12.8 m/s, down. O e. 5.0 m/s, down.
