1 Impact A bullet of mass 200 g is traveling horizontally due east with a speed of 400 m/s when it strikes a block of mass 1.8 kg that is initially at rest on a smooth table. After striking the block, the bullet is embedded in the block and the two objects move together as one unit. (a) What is the magnitude and direction of the velocity of the block/bullet combination immediately after impact? (b) What is the magnitude and direction of the impulse from the block to the bullet? (c) What is the magnitude and direction of the impulse from the bullet to the block? (d) If it took 3 ms for the bullet to decelerate from 400 m/s to the final speed after impact, what was the average force between the block and the bullet during this time? (e) If it took 3 ms for the block to accelerate to the final speed after impact, what was the average force between the bullet and the block during this time?

6. A 0.25 kg ball bounces off a vertical wall as shown. The speed of the ball just before hitting the wall is 8 m/s and just afterwards is 6 m/s. The collision takes 0.1 sec. a. What is the impulse delivered to the ball? Write in component vector form. y 30° 30 What is the average force that the wall exerts on the ball during the collision? Remember the impulse-momentum relation refers to the net force; you will have to take gravity into account when you do your analysis. c. What is the average force that the ball exerts on the wall during the collision? d. Repeat your calculation for the average y force on the ball using Newton's 2nd law and the free body diagram method. Make sure your answer agrees with your answer for (b).
