A man of mass 80 kg is standing stationary in the middle of a train carriage. The train is moving horizontally (towards the right) with a constant speed of 20 m/s, 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...

correct answer is 1.pls explain well..
A long horizontal rod has a bead which can slide along its length and is initially placed at a distance L from one end A of the rod. The rod is set in angular motion about A vwith a constant angular acceleration α. If the coefficient of friction between the rod and bead is μ, and gravity is neglected, then the time after which the bead starts slipping is 关 Ll (4) infinitesimal

A thin, uniform, metal bar, 3 m long and weighing 80 N , is hanging vertically from the ceiling by a frictionless pivot. Suddenly it is struck 1.3 m below the ceiling by a small 4-kg ball, initially traveling horizontally at 14 m/s . The ball rebounds in the opposite direction with a speed of 5 m/s . Find the angular speed of the bar just after the collision.
