An object of mass m swings in a horizontal circle on a string of length L that tilts downward at angle θ. Find an expression for the angular velocity ω in terms of g, L and angle θ. Furthermore, if a student ties a 350 g rock to a 1.8m long string and swings it around her head in a horizontal circle. At what angular speed, in rpm, does the string tilt down at a 10∘ angle? Lastly, do you know of any resources/ websites where I would be able to watch good detailed videos about circular motion problems/ to find practice problems (for circular motion in mechanics)? Thank you: )

Consider an annular disk rolling down an inclined plane. The annular disk has mass 154 [g], inner radius 8.00 [cm] and outer radius 12.0 [cm]. The inclined plane has a slope that forms an angle of 44.6° with the ground. A. Suppose that the coefficient of static friction ?s is large enough so that the annular disk rolls without slipping. What is the magnitude of the translation acceleration felt by the annular disk's center of mass in the direction parallel to the slope? B. What is the minimum value that the coefficient of static friction ?s must take so that the annular disk rolls without slipping?

At amusement parks, there is a popular ride where the floor of a rotating cylindrical room falls away, leaving the backs of the riders “plastered” against the wall. Suppose the radius of the room is 7.9 m and the coefficient of friction between the rider and the wall is 0.839, what is the minimum the safe speed of the wall for the rider not to drop when the floor falls away. Use g=9.8 m/s2.
A box descends a ramp and lands on a surface. The box exits the side of the table as it meets the bottom of the tamp, becoming a horizontal projectile. It lands x metres away from the table. The same ramp may be rolled down by a solid sphere with the same coefficient of friction, mass, and height. Will the sphere land a long way away? fewer than a lot more At a similar size B.

ANSWER QUICK! Ive read the honor code and it says that their a question can have up to 3 subparts (i.e. part a, b, and c). So please answer all questions. A fire hose held near the ground shoots water at a speed of 12.5 m/s. At what angle(s) should the nozzle point in order for the water to land 6.69 m away? What is the lowest angle in radians? What is the larger angle in radians?
Please answer vertically, not horizontally so that no steps are miscalculated for this problem. A unicorn is standing on a rotating platform so that it can be admired from every angle. The platform is 5 m in radius and rotates every 8 seconds (otherwise known as 1/8 of a rotation per second). What coefficient of friction must the unicorn's hooves have to keep him from slipping over the edge? This answer is not shown correctly on bartleby. Would he need a higher or lower coefficient of friction to stand closer to the center of the rotating platform? Explain.
A long limp spring is hung from a beam; the spring's bottom is 660 mm above the table. A 0.50 kg cylinder is hooked to the spring's bottom while the spring hangs relaxed. When the cylinder is dropped, it turns around just above the table, where the spring's bottom had been stretched to 10 mm above the table. What is the cylinder's velocity, half-way to the bottom turn-around?
