Baby Huey rolls a rubber ball (a hollow sphere) of mass M and radius R up a hillside, giving it an initial kinetic energy of Ki. It rolls over the top of the hill of height h and keeps going. The ball rolls without slipping. a) Do a good, well labeled diagram for this. b) Find the general formula for the total kinetic enerty Ktot of the ball when it has a translational velocity v. Write your answer in terms of M, R, and v only. Assume it rolls without slipping. c) Given the height of the hill is h=1.45m ,Ki = 27J, R = 0.243 m, and M = 0.9 kg, find the total kinetic energy Kf at the top of the hill. d) Find the translational velocity vf at the top of the hill. c) Find the rotational velocity wf at the top of the hill.
2.00 P Flag question Write down an expression for the net force on a simple pendulum of the mass m along (tangentially to) the arc of motion in the gravitational field with strength g. Please use "*" (without the quotes) for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. For exponents (e.g. A²) use A*A or A^2 notation: thus A³/B should appear as either A*A*A/B or A^3/B. For greek letters use "theta" (without the quotes) and for trigonometric functions use "cos", "tan", "sin" (without the quotes). Thus for Acoso use A* cos theta. Please use the "Display response" button to check you entered the answer you expect. g↓ INIL 0 Answer: Display response m are of motion
The pedals of a bicycle are mounted on a bracket whose centre is 27.5 cm above the ground. Each pedal is 17.5 cm from the bracket. Assume that the bicycle is pedalled at a rate of 10 cycles per minute. 1. Draw a graph showing the height of one of the pedals above the ground for the first 2 cycles with time in seconds. Assume that the pedal starts at the topmost position at t=0. 2. Write an equation modelling the height of the pedal as a function of time. 3. When is the pedal 15 cm above the ground for the 6th time?
