A 0.00555−kg bullet traveling horizontally with a speed of 1.00×103 m/s enters a 20.0−kg door, embedding itself 20.0 cm from the side opposite the hinges as in the figure below. The 1.00−m-wide door is free to swing on its hinges. (a) Before it hits the door, does the bullet have angular momentum relative to the door's axis of rotation? Yes No Explain. This answer has not been graded yet. (b) Is mechanical energy conserved in this collision? Answer without doing a calculation. Yes No (c) At what angular speed does the door swing open immediately after the collision? (The door has the same moment of inertia as a rod with axis at one end.) rad/s (d) Calculate the energy of the door-bullet system. (Enter the kinetic energy of the door-bullet system just after collision.) J Determine whether the energy of the door-bullet system is less than or equal to the kinetic energy of the bullet before the collision. less than equal

Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.62 m/s, and bumper car 2 is traveling 60.0∘ south of west at 10.00 m/s. After they collide, bumper car 1 is observed to be traveling to the west with a speed of 3.28 m/s. Friction is negligible between the cars and the ground. (a) If the masses of bumper cars 1 and 2 are 592 kg and 633 kg respectively, what is the velocity of bumper car 2 immediately after the collision? (Express your answer in vector form. Enter your answer to at least three significant figures.) v→2 = m/s (b) What is the kinetic energy lost in the collision?

A 1,440-N crate is being pushed across a level floor at a constant speed by a force F→ of 200 N at an angle of 20.0∘ below the horizontal, as shown in the figure a below. a b (i) (a) What is the coefficient of kinetic friction between the crate and the floor? (Enter your answer to at least three decimal places.) (b) If the 200−N force is instead pulling the block at an angle of 20.0∘ above the horizontal, as shown in the figure b, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in part (a). m/s2
