The wheel in the figure to the right has eight equally spaced spokes and a radius of 30 cm. It is mounted on a fixed axle and is spinning at 25 rev/s You want to shoot a 20-cm-long arrow paraliled to this asle and through the wheel without hit- ting any of the spokes. Assume that the arrow and spokes are very thin (a) What minimum speed must the arrow have? Does it matter where between the axle and the...
t is your acceleration while sitting in your chair. The latitude of Corvallis is 44.4'.(b) What is percent difference in the magnitude of your apparent weight due to the rotational mo- tion? (c) How long would a day have to be for the acceleration to be equal in magnitude to 9.8 m/s2?
Chapter 10, Problem 007 e wheel in the figure has eight equally spaced spokes and a radius of 28 crn. It is mounted on a fixed axle and is spinning at 5.0 rev/s You want to shoot a 21m the wheel without hitting any of the spokes. Assume that the arrow and the spokes are very thin. What minimum speed must the arrow have? "row shi-n" ad' 써"rough Units Number +/-5%
3. An electrical motor spins at 1000 rpm and is slowing down at a rate of 10 rad/s (a) If the motor radius is 7.165 cm, what is the linear acceleration of the edgc of the motor? (b) How long will it take to decrease it's angular velocity by 75%
can someone help me with questions 3 and 4 please !! 3. A machine part has the shape of a solid uniform sphere of mass 205 g and diameter 4.50 cm. It is spinning about a frictionless axle through its center, but at one point on its equator it is scraping against metal, resulting in a friction force of 0.0200 N at that point. Find its angular acceleration. Let the direction the sphere is spinning be the positive sense of...
Work out the highlighted questions (3-6) clearly and with units, please. Thanks! 4/5 a the minimum kinetic energy at the apping point? (C) Use conservation of energy to determine the minimum angular velocity of the block just after the collision, (d) then use conservation of angular momentum during the collision to find the initial speed of the bullet vo. (Hint: Ignore the mass of the bullet after the collision. The moment of inertia of the cube about its bottom-right edge...
