- An experiment is performed in an ideal condition to find out the velocity of a particle obeying the equation S=vtS=vt where the distance travelled (S)(S) inside a labeled glass tube by a particle with an uniform velocity (v)(v) is measured with respect to time taken (t)(t). The data collected by repeating the experiment five times is shown in the table below If we use the method to minimize the squared sum error, what is the most likely velocity of the particle among the given options? 2.5 1.5 2 1A boxer's fist and glove have a mass of m = 0.72 kg.

THANKS!!You encounter a moving walkway that is 75 mm long and has a speed of 1.9 m/sm/s relative to the ground.How long would it take you to cover the 75 mm length of the walkway if, once you get on the walkway, you turn around and start walking in the opposite direction with a speed of 1.4m/s relative to the walkway?
- Explain why, when defining the length of a rod, it is necessary to specify that the positions of the ends of the rod are to be measured simultaneously.e) Consider a lab in which a detector 2 is located a distance of 3.0 m from detector 1 in the positive x-direction. A particle passes through the detector 2 at a time of t = 0 ns and is moving directly toward detector 1 at a constant speed of 0.80 c, where c is the speed of light. The particle emits a photon at a time of t = 5 ns, also traveling directly toward detector 1. All values in this question part are in the rest frame of the lab. Draw a spacetime diagram in this rest frame in units of light-nanosecond (Lns), with the worldline of detector 1 starting at the origin of the coordinate system. Draw the worldlines for the detector 1, particle, and the photon. Write out all your calculations.Prove 1.)
