A4.2 kg block is initially at rest on a horizontal frictionless surface when a horizontal force in the positive direction of an x axis is applied to the block. the force is given by , where x is in meters and the initial position of the block is x = 0. (a) what is the kinetic energy of the block as it passes through x = 3.1 m? (b) what is the maximum kinetic energy of the block between x = 0 and x = 3.1 m

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)
