c.) Find the coefficient of kinetic friction (uk) of the friction patch. Use the energy method (including friction) to get it. (Also try it with the older force
methods-- make sure both methods give the same answer!)

f.) Examining parts d-e, which could have been done with the energy method? With older methods? With either? If both methods would work, re-do
the part with the other method (the one you did not already use) and show it gives the same result. If you cannot use both methods, explain why the
other method doesn't work.
Finally:
g.) Elmer Fudd (unknown mass) wishes to repeat Bugs Bunny's feat. Assuming he starts from rest, what is the minimum height up the initial hill that
he must start, in order to successfully swing around the top of the swing set bar?
Please express your answer as a number and as a multiple of the circle's radius.

Transcribed Image Text:Bugs Bunny (m=32 kg) starts at rest atop a h;=33 m tall hill, and then slides down. After that, Bugs:
I.) slides into a swing set at the bottom of the hill, which has a R = 11 m long chain. He swings up and over the bar, with the chain managing to stay
taut. (Labelled points A, B & C are at the bottom, side and top of the loop respectively.)

II.) continues on flat ground, where he then hits a friction patch which is L=41.25 m long, from which he exits (at labelled point D) at speed vp

III.) slides off a cliff that is hp=17 m tall, into a lake.

- 10. Wedge Hammer A B 45° -450 mm Fig. 3.20 Neglecting the small amount by which the hammer rises after passing through the vertical through A and assuring that the hammer does not rebound, find the value of R Fig. 3.20 shows a tilt hammer, hinged at 0, with its head A resting on top of the pile B. The hammer, including the arm OA, has a mass of 25 kg. Its centre of gravity G is 400 mm horizontally from O and its radius of gyration about an axis through G parallel to the axis of the pin O is 75 mm. The pile has a mass of 135 kg. The hammer is raised through 45° to the position shown in dotted lines, and released. On striking the pile, there is no rebound. Find the angular velocity of the hammer immediately before impact and the linear velocity of the pile immediately after impact. Neglect any impulsive resistance offered by the earth into which the pile is being driven.

- A projectile object reaches a height of 430 m, if it is fired straight up using a spring-loaded gun. Using the same gun, what is the maximum height (m) that can be reached by the projectile if it fired at an angle of 31 ° from the vertical?arrow_forwardHello. Answer is s=0.42m (how far the spring goes down before stopping the object falling). I am uploading this question as the example answer's working out was bad I find it hard to follow. I would like to see working out how the calculations equate to the answer being s=0.42marrow_forwardFrom rest a balloon begins to rise. the Balloon experiences a lift due to a buoyant force of 8000 N. 1.
