A small ball of mass 0.400 kg is attached by a massless string to a vertical rod that is spinning (as shown in the figure below). When the rod has an angular velocity of 5.20 rad/s, the string makes an angle of 30.0 \deg with respect to the vertical. Part 1 If the angular velocity is increased to 11.0 rad/s, what is the new angle of the string? degrees Part 2 Calculate the angular momentum of the ball with the original angular velocity. Part 3 Calculate the angular momentum of the ball with the new angular velocity.

Tutorial Find the mass (in kg) of Neptune from the orbital parameters of its moon, Proteus. The radius of Proteus's orbit about Neptune is 1.18 x 10° m and its period is 1.12 days. How many Earth masses is this? Part 1 of 3 In order to find the mass, we need to combine the formulas for circular velocity and speed of the moon in its orbit. 2ar V = P GM V = Setting them equal gives: GM 2ar Squaring both sides and solving for mass: GM 2ar 2 Find the mass of Neptune from the orbital parameters of its moon, Proteus. The radius of Proteus's orbit about Neptune is 1.18 x 10° m and its period is 1.12 days. Once you solve for the mass, does the exponent of the radius change? What is the exponent for r? 4x2 M = (rm)" (P? G Submit Skip (you cannot come back)

Disk - 0.20 m A coin C of mass 0.050 kg is placed on a horizontal disk at a distance of 0.20 m from the center, as shown above. The disk rotates at a constant rate in the clockwise direction as seen from above. The coin does not slip, and the time it takes for the coin to make a complete revolution is 1.2 s. a. The figure below shows the disk and coin as viewed from above. Draw and label vectors on the figure below to show the instantaneous acceleration and linear velocity vectors for the coin when it is at the position shown. b. Determine the speed of the coin. c. The rate of rotation of the disk is gradually increased. The coefficient of static friction between the coin and the disk is 0.50. Determine the speed of the coin when it just begins to slip. d. If the experiment in part (c) were repeated with a second, identical coin glued to the top of the first coin, how would this affect the answer to part (c) ? Explain your reasoning.
