While sitting in physics class one day, you begin to ponder the workings of the analog clock on the classroom wall. You notice as the hands sweep in a continuous motion that there are exactly t = 51 minutes left in class. Feedback:  0%  deduction per feedback.   14% Part (c)  Through what angle (in radians) will the hour hand sweep before the end of class?

Different situation now. You re out in space, on a rotating wheel-shaped space station of radius 743 m. You feel planted firmly on the floor , due to artificial gravity. The gravity you experience is Earth-normal, that is, g = 9.81 m/s^2. How fast is the space station rotating in order to produce this much artificial gravity? Express your answer in revolutions per minute (rpm).     0.115 rpm     85.4 rpm     0.549 rpm     1.097 rpm

The figure below shows an object initially at point A traveling in the +x-direction. It turns in a circular path at constant speed until it is traveling in the +y-direction at point C. The quarter-circle arc from A to C is 245 m in length, and the particle moves from A to C in 38.0 s. Point B on the path is 35.0° below the x-axis. 0 35.0⁰ (a) What is the speed of the object (in m/s)? m/s Need Help? (b) What is the magnitude and direction of the acceleration when the object is at point B? (Enter the magnitude in m/s² and the direction in degrees counterclockwise from the +x-axis.) magnitude m/s² direction Read It counterclockwise from the +x-axis

Trent is running along a circular track that has a radius of 45 meters. Trent starts at the 3-o'clock position and travels in the CCW direction, stopping after 106 meters. Imagine an angle with a vertex at the center of the circular track that subtends the path Trent has traveled. When Trent stops, what is his horizontal distance from the center of the track?

After losing control, a hot air balloon is adrift on the wind, and travels north for 4.1 km. the wind shifts and blows the balloon south for 10.8 km. After one more shift, it blows North for another 11.1 km. What is the magnitude of the resulatant displacement of the hot air balloon?

A small object of mass 0.500 kg is attached by a 0 0.650 m-long cord to a pin set into the surface of a frictionless tabletop. The object moves in a circle on the horizontal surface with a speed of 6.91 m/s.1. What is the magnitude of the radial acceleration of the object?2. What is the tension of the cord?

An object is moving counter-clockwise in uniform circular motion at a constant speed of 3 m/s in a circle of radius 1.2 m. The magnitude of radial acceleration is 7.5 m/s?. Point A is at an angle of 15 degrees from the x axis. Sketching the position, velocity, and acceleration vectors may be helpful. A. Calculate the x and y components of the position vector for point A. B. Calculate the x and y components of the velocity vector for point A. C. Calculate the x and y components of the acceleration vector for point A. +y A +x 15° (0,0)
