Acertain spring exerts a nonlinear force given by f(x) = −60x − 18x2 , where x is in meters and f is in newtons. a 0.90-kg block on a frictionless, horizontal surface is attached to the spring at x = 0. the block is pushed to x = −0.50 m and is then released. a) the work done by the spring on the block as it moves from x = −0.50 m to x = 0? b) the block’s speed when it reaches x = 0 c) what are the units of the coefficient with value –18?

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.)
