- Hello, based on the table can you please help me do a, b and c?arrow_forwardThe space bus is 2.0 km long in its own frame and moves towards planet earth at a speed of 0.6c. Jim is on the bus while Carl is on earth. Jim is sitting at the back of the bus and launches a projectile towards the front of the bus at a speed of 0.4c. Ignore any acceleration times or energy considerations. (a) How fast does Carl measure the projectile to be moving? (b) How long does Carl measure the bus in his frame? (c) How long would Carl determine it would take for the projectile to reach the front of the bus?arrow_forwardEach of the strobe photographs (a), (b), and (c) as shown was taken of a single disk moving toward the right, which we take as the positive direction. Within each photograph the time interval between images is constant. For each photograph, prepare graphs of x versus t, υx versus t, and ax versus t, vertically aligned with their time axes identical, to show the motion of the disk. You will not be able to place numbers other than zero on the axes, but show the correct shapes for the graph lines.arrow_forward

Unfortunately, your garage is only 4.0 m long.

- An experimentalist in a laboratory finds that a particle has a helical path. The position of this particle in the laboratory frame is given by r(t)=Rcost+Rsint+vztk where R, vz, and are constants. A moving frame has velocity (vM)L=vzk relative to the laboratory frame. a. What is the path of the particle in the moving frame? b. What is the velocity of the particle as a function of time relative to the moving frame? c. What is the acceleration of the particle in each frame? d. How should the acceleration in each frame be related? Does your answer to part (c) make sense? Explain.arrow_forwardQuite apart from effects due to Earth’s rotational and orbital motions, a laboratory reference frame is not strictly an inertial frame because a particle at rest there will not, in general, remain at rest; it will fall. Often, however, events happen so quickly that we can ignore the gravitational acceleration and treat the frame as inertial. Consider, for example, an electron of speed v =0.992c, projected horizontally into a laboratory test chamber and moving through a distance of 20 cm. (a) How long would that take, and (b) how far would the electron fall during this interval? (c) What can you conclude about the suitability of the laboratory as an inertial frame in this case?arrow_forwardwo particles are traveling through space. At time tt the first particle is at the point (−4+t,3−3t,3+t) and the second particle is at (−12−t,19+t,−9−2t) Describe the two paths in words. Then determine if the two particles collide, cross, or neither cross nor collide. If they collide or their paths cross, indicate where.arrow_forward
