Question: A force in the negative direction of an x axis is applied for 27 ms to a 0.40 kg ball initially moving at 14 m/s

A force in the negative direction of an x axis is applied for 27 ms to a 0.40 kg ball initially moving at 14 m/s in the positive direction of the axis. The force varies in magnitude, and the impulse has magnitude 32.4 N ∙ s. What are the balls?
(a) Speed and
(b) Direction of travel just after the force is applied? What are?
(c) The average magnitude of the force and
(d) The direction of the impulse on the ball?
