- An astronaut lost in space is far from any other mass (i.e.,gravity is negligible). He swings a weight of mass m = 0.5 kg that is tiedto a string, and it undergoes counterclockwise circular motion with aradius r = 2 m. The mass does a revolution once every 3 seconds.a) Draw the velocity and acceleration vectors of mass m at points p1,p2, and p3.b) What is the velocity?c) What is the centripetal force?d) What is the magnitude of the tension force in the string?A "swing" ride at a carnival consists of chairs that are swung in a circle by 16.9 m cables attached to a vertical rotating pole, as the drawing shows. Suppose the total mass of a chair and its occupant is 137 kg. (a) Determine the tension in the cable attached to the chair. (b) Find the speed of the chair.A "swing" ride at a carnival consists of chairs that are swung in a circle by 12.4 m cables attached to a vertical rotating pole, as the drawing shows. Suppose the total mass of a chair and its occupant is 135 kg. (a) Determine the tension in the cable attached to the chair. (b) Find the speed of the chair.
- 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.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 0/99In 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?
- A 0.7-kg mass attached to the end of a string swings in a vertical circle (radius = 2.3 m). When the mass is at the lowest point on the circle, the speed of the mass is 15 m/s. What is the magnitude of the force of the string in newtons (i.e. tension in the string) on the mass at this position?A rubber ball is attached to a 1.44-meter string and spun in a horizontal circle. The tension in the string is 2.91 N. It takes 0.644 s for the ball to complete one revolution. Determine the mass (in kg) of the ball.A ball of mass 4.7 kg and a diameter of 68.2 cm is attached to a string of length 1.1 m. It moves in a circular path at constant speed, 3.0 m above the ground.
