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?
