A 100 kg football linebacker moving a 2 m/s tackles head on an 80kg halfback running 3 m/s. Assume the two players were initiallyrunning directly at one another. Neglecting the effects due to digging in of cleats.A. The halfback will drive the linebacker backwardsB. Neither player will drive the other backwardsC. The linebacker will drive the halfback backwardD. This is a simple example of an elastic collision.
Four particles, one at each of the four corners of a square with 3m-long edges, are connected by massless rods. The masses of the particles are m1 = m3 = 4kg and m2 = m4 = 5kg. Determine the moment of inertia of the system about the z axis.
