For a particle rotating about a fixed axis with angular velocity that changes, which of the following statements is TRUE? There is neither radial nor tangential acceleration. There is only tangential acceleration. There is no angular acceleration. There is only radial acceleration. There are both radial acceleration and tangential acceleration.

How do I find the tangential speed of a ball going in uniform circular motion, in the problem I'm working on, a 1.3 m long string makes a 48.8 degree angle below the hoizontal. I am confused as to how I find the w to plug into the Vt=rw equation to get the tangential speed. Thanks for your help!

A diver runs horizontally off the end of a diving tower 3.5m above the surface of the water with an initial speed of 2.5 m/s. During her fall she rotates with an average angular speed of 2.6 rad/s How many revolutions has she made when she hits the water? Express your answer using two significant figures.Δθ= (?) rev

If the magnitudes of the velocity and acceleration of point A of the rotating bar are VA - 3 m/s and aA = 27 m/s2, what is the magnitude of the angular velocity co?a=0.58 m, b=0.14 m, and c=0.81 m. B b 0), a

1. The horizontal circular platform weighs 500 lb and has a radius of gyration of kz = 8 ft from the z-axis passing through O. The platform is free to rotate about the z-axis and is initially at rest. A person having a weight of 150 lb begins to run along the edge in a circular path of radius 10 ft. If they maintain a speed of 4 ft/s relative to the platform, determine the angular velocity of the 10 ft platform. Neglect friction. I don't think we have dealt with relative velocity in this context, but it follows our earlier relative velocity treatment. Here all speeds are in the t-direction. vp is the speed of the person, and vp is the speed of the disk at the location of the person. Then vp = vp + Vp/D, same as before. You are given vpp = 4 ft/s.

A lady bug (L) and gentleman bug (G), of equal mass, are both sitting on a turntable that is rotating at a constant rate, as shown in the figure. The ladybug is further from the axis of rotation. Which of the following statements are true regarding this situation? L and G both have the same radial acceleration L has a greater radial acceleration than G L has a smaller radial acceleration than G L and G both have the same tangential acceleration L has a greater tangential acceleration as G L has a smaller tangential acceleration as G L and G both have the same net force acting on them L has a greater net force acting them than G L has a smaller net force acting on them than G

Starting from rest, an airplane propeller begins to rotate with an angular acceleration a = 0.0600 rad/s2. The propeller radius is 60.0 cm. After exactly 4.00 seconds, calculate the total linear acceleration of the tip of the propeller. (The total linear acceleration is the vector combination of the tangential acceleration and the centripetal acceleration.) r= 60.0 cm

If a centrifuge pushes the astronauts to 5g's with a radius of 10m, (i) what is the angular velocity of the centrifuge? (ii) what is the tangential velocity? (iii) what would be the angular velocity if the centrifuge worked at 9g's? (iv) in a uniform circular motion, which stays constant, the magnitude of the velocity vector or the direction of the velocity vector
