A baseball with a mass of 154 g is thrown horizontally with a speed of 38.9 m/s (87 mi/h) at a bat. The ball is in contact with the bat for 1.20 ms and then travels straight back at a speed of 45.0 m/s (101 mi/h). Determine the average force (in N) exerted on the ball by the bat. Neglect the weight of the ball (it is much smaller than the force of the bat) and choose the direction of the incoming ball to be positive. (Indicate the direction with the sign of your answer.) N

A 0.160-kg hockey puck is moving on an icy, frictionless, horizontal surface. At t = 0, the puck is moving to the right at 3.00 m/s. (a) Calculate the velocity of the puck (magnitude and direction) after a force of 25.0 N directed to the right has been applied for 0.050 s. (b) If, instead, a force of 12.0 N directed to the left is applied, how long would it take to stop the puck?
A 475-gram ball is traveling horizontally at 12.0 m/s to the left when it is suddenly struck horizontally by a bat, causing it to reverse direction and initially travel at 8.50 m/s to the right. If the bat produced an average force of 1275 N on the ball, for how long (in milliseconds) was it in contact with the ball?
If a 0.50 kg block initially at rest on a frictionless, horizontal surface is acted upon by a force of 4.2 N for a distance of 4.3 m, then what would be the block's velocity (in m/s)?
A duck has a mass of 2.50 kg. As the duck paddles, a force of 0.120 N acts on it in a direction due east. In addition, the current of the water exerts a force of 0.220 N in a direction of 53.0° south of east. When these forces begin to act, the velocity of the duck is 0.130 m/s in a direction due east. Find (a) the magnitude and (b) the direction (relative to due east) of the displacement that the duck undergoes in 2.60 s while the forces are acting. (Note that the angle will be negative in the south of east direction.)
