I whirl John (mass 0.27 kg) over my head in a circle. There is a spring scale between my hand and the string, so I can measure the force of tension in the string, which I find to be 2.12 N. I measure the length of the string (the radius of the circle) and find it to be 1.34 m. Assuming that John's speed is not changing, how fast is he going?
Leilani loads luggage into a Hawaiian Air passenger plane bound for Vegas using a conveyor belt tilted at an angle of 20°. She places a few pieces of luggage onto the belt before it starts to move. When she turns the belt on it takes 0.70 s for it to reach a top speed of 1.2 m/s. Does the luggage slip? Assume µs = 0.50 between the luggage and the belt. (12 points) %3D
It is well known that runners run more slowly around a curved track than a straight one. One hypothesis to explain this is that the total force from the track on a runner's feet--the magnitude of the vector sum of the normal force (that has average value mgmg to counteract gravity) and the inward-directed friction force that causes the runner's centripetal acceleration--is greater when running around a curve than on a straight track. Runners compensate for this greater force by increasing the time their feet are in contact with the ground, which slows them down. For sprinters running at 8 m/s around a curved track of radius 16 m, how much greater (as a percentage) is the average total force on their feet compared to when they are running in a straight line?
A 1.5kg rock is tied to the end of a 1.25m string and is swung in a vertical circle at a constant speed of 4.5 m·s−1. If the string breaks when the tension is 135 N, calculate the maximum speed that the rock can be swung without breaking the string?

A toy aeroplane of mass m = 1,80 kg is attached to a string of length e = 33.0 m and flys in uniform circular motion in a horizontal plane around the centre of its motion. The plane has an engine which generates thrust that keeps the plane moving at a speed of v = 30.7 km/hr. (a) What is the period of the circular motion? Period = S (b) What is the tension in the string holding the aeroplane in its circular motion? Tension = Part 3) A block sits on a sloping plane that can have its angle to the vertical p varied. The angle o initially starts at a value of 90°, and the slope is raised until at an angle o E 33.2° the block starts to slide down the slope. Calculate the coefficient of static friction for this block on this slope.
An object of mass m = 5.0 kg undergoes uniform circular motion in the r-y plane. The radius of its circular motion is R = 2.0 m. From the view shown in the diagram, it circles in the clockwise sense. At a certain moment the velocity of the object is T = (-3.0,0,0) m/s. +y (a) At that same moment, what is the net force (a vector) on the object? Calculate a numerical value and put your vector answer in component form. How much time does it take the object to complete eight-and-a-half revolu- (b) tions?
Life scientists use ultracentrifuges to separate biological components or to remove molecules from suspension. Samples in a symmetric array of containers are spun rapidly about a central axis. The centrifugal acceleration they experience in their moving reference frame acts as "artificial gravity" to effect a rapid separation. If the sample containers are 11.9 cm from the rotation axis, what rotation frequency is required to produce an acceleration of 1.85-105 g? Submit Answer Tries 0/99
In the game of tetherball, a ball is hung from a vertical pole via a 0.75m rope. The rope is allowed to pivot freely from the top of the pole so the ball can swing around the pole. If the angle of the rope is 30° with respect to the pole, how much time does it take the ball to make one complete revolution around the pole?
