is 0.80 m and the disk is rotating with an angular speed of 38 rpm. The coefficient of friction between the bugs and the disk are us = 0.80 and uk= 0.60. What is the magnitude
of Buzz's acceleration, in m/s2?
Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your

- You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 50° from the edge of the building with an initial velocity of 10 m/s and lands 20 meters away from the wall of the building. You will be asked to find how tall the building is that the child is standing on. Draw a picture showing the trajectory of the ball. Find the x- and y-components for the initial velocity. Group of answer choices A. v0x = 7.7 m/s; v0y = 6.4 m/s B. v0x = 6.4 m/s; v0y = 7.7 m/s C. v0x = 0 m/s; v0y = 10 m/s D. v0x = 10 m/s; v0y = 0 m/sarrow_forwardA friend is holding a potato gun at a 40 degree angle from the very bottom. It sends out a potato which travels a horizontal distance of 850m. a. How long does it take the potato to hit the ground? b. Your friend has unfortunately not so much as held the potato gun as wedged it in the ground, supporting it vertically but not horizontally. As a result, the bottom end that they hold doesn't move, but the top of the gun moves backward in a circle due to the torque of the recoil. If the potato gun is 2 meters long, and your friend's face is also about 2 meters above the ground, so that it collides with the potato gun once the gun has become vertical, then how quickly is the gun moving when it hits your friend's face?arrow_forwardThis is a Dynamics of Rigid Bodies subject.

We examine the projectile motion of a disk on an inclined plane that makes an angle o (sin o = 0.1) with the horizontal. The y-axis is oriented along the inclined plane and the x-axis along the plane perpendicular to the y-axis, as shown in the figure. At t = 0, the disk is thrown from the origin of the coordinate system with an initial velocity V that makes the angle 0 = 53° with the x-axis (sin 53° = 0,8, cos 53° = 0,6). The frequency of the spark timer is 10 Hz.
