Aforce in the negative direction of an x axis is applied for 25 ms to a 0.50 kg ball initially moving at 16 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 not enough information to decide -x direction (c) what is the average magnitude of the force? n (d) what is the direction of the impulse on the ball? -x direction not enough information to decide +x direction
