A force in the negative direction of an x axis is applied for 34 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.
(a) What is the ball's speed just after the force is applied?
m/s
(b) What is the ball's direction of travel just after the force is applied?
-x direction
+x direction
not enough information to decide
(c) What is the average magnitude of the force?
N
(d) What is the direction of the impulse on the ball?
