Please can you help with this question? solve all the partsuntil part f. some are already solved.
A 0.00600 kg bullet traveling horizontally with speed 1.00 x 10³ m/s strikes a 16.1 kg door, embedding itself 10.6 cm from the side opposite the hinges as shown in the figure below. The 1.00 m wide door is free to swing on its frictionless hinges. Hinge (a) Before it hits the door, does the bullet have angular momentum relative the door's axis of rotation? Ⓒ Yes O No (b) If so, evaluate this angular momentum (in kg - m²/s). (If not, enter zero.) kg-m²/s If not, explain why there is no angular momentum. (c) Is mechanical energy of the bullet-door system constant in this collision? Answer without doing a calculation. Ⓒ Yes Ⓒ No (d) At what angular speed (in rad/s) does the door swing open immediately after the collision? rad/s (e) Calculate the total energy of the bullet-door system and determine whether it is less than or equal to the kinetic energy of the bullet before the collision. (Enter your answers in J.) KE= KE, = (f) What If? Imagine now that the door is hanging vertically downward, hinged at the top, so that the figure is a side view of the door and bullet during the collision. What is the maximum height (in cm) that the bottom of the door will reach after the collision? cm
