Circular Motion: Consider a joint performing a counterclockwise circular motion of radius R = const. In this sense, using a polar coordinate system, one asks: a) Make an illustration (diagram of forces) and then Definition (I) of the angular velocity; (II) angular acceleration; and (III) acceleration centripet. (#) b) Make an illustration (diagram of forces) and then make the Vector relation (I) between linear and angular velocities; and (II) between linear and angular accelerations. (#)
A car is slowing down in a straight road.What direction does its angular velocity point? And what direction does its angular acceleration point?Explanation. A plumb bob is generally to hang vertically downwards – ie, towards the center of the Earth.(it maybe not always true) By drawing a free-body diagram and considering the centripetal acceleration of a plumb-bob (at 45o N latitude), explain why. indicate the direction (north, south, east, or west) that the plumb bob will hang. Two particles execute simple harmonic motion with the same amplitude. One particle has twice the frequency of the other. Compare their maximum velocities and accelerations.
Suppose that you are holding a pencil balanced on its point. If you release the pencil and it begins to fall, what will be the angular acceleration when it has an angle of 10.0 degrees from the vertical? Calculate the time t for the pencil to hit the ground, assuming that it falls from standing perfectly vertical and maintains this angular acceleration. Express your answer in seconds. a=-17.0 rad/s2
An amusement park ride called the Rotor debuted in 1955 in Germany. Passengers stand in the cylindrical drum of the Rotor as it rotates around its axis. Once the Rotor reaches its operating speed, the floor drops but the riders remain pinned against the wall of the cylinder. Suppose the cylinder makes 24.5 rev/min and has a radius of 3.70 m. What is the minimum coefficient of static friction ?sμs between the wall of the cylinder and the backs of the riders?
Global warming is a cause for concern because even small changes in the Earth’s temperature can have significant consequences. For example, if the Earth’s polar ice caps were to melt entirely, the resulting additional water in the oceans would flood many coastal areas. Model the polar ice as havingmass 2.30 × 1019 kg and forming two flat disks of radius 6.00 × 105 m. Assume the water spreads into an unbroken thin, spherical shell after it melts. Calculate the resulting change in the duration of one day both in seconds and as a percentage.
In this problem you will measure the gravitational constant in a series of “observational experiments,” making use of Newton’s law of gravitation and second law of motion as well as Kepler’s third law of planetary motion a)Since measuring the centripetal acceleration of an orbiting body is rather difficult, an alternative approach is to use the body’s rotational period instead. Enter an expression for the gravitational constant, in terms of the distance between Earth and the moon, RME, Earth’s mass,ME, and the moon’s period of rotation around Earth, T. b)Using the expression you entered in part (b) and taking the rotational period of the moon to be T = 27.1 days, what value would Newton have calculated for the gravitation constant, in units of N⋅m2/kg2? Take ME = 5.95×1024 kg and RME = 3.86×108 m. c) Suppose a rocket is launched as described in part (d) with an initial speed of vi = 494 m/s and attains a peak altitude of H = 12.7 km above the surface of Earth. Taking ME = 5.95×1024 kg…
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 = 41 minutes left in class. What is the magnitude of the angle (in radians) that the minute hand sweeps before the end of class? What is the magnitude of the angle (in radians) that the hour hand sweeps before the end of class? Calculate the angular speed of the second hand in radians per second. Calculate the angular speed of the minute hand in radians per second. Calculate the angular speed of the hour hand in radians per second. Is the angular acceleration of the second, minute, and hour hands the same? Pick the most accurate response.
According to basic concepts of particle rotation problems and rigid bodies, analyze the statements and determine which of them are true. I - in a circular motion, the linear velocity vector is always perpendicular to the resulting acceleration vector; II - if a particle performs a circular movement (of radius R) with constant angular velocity, the tangential acceleration over it is null; III - the Moment of Inertia of a particle system is a scalar quantity whose value is independent of the choice of rotation axis; Choose one:a) Only Ib) Only I and IIIc) Only II and IIId) Only I and IIe) None of the alternatives are truef) Only IIg) All alternatives are trueh) Only the III
Engineering Dynamics A ball of mass m is moving along a vertical semi-cylinder of radius R as it is guided by the arm OA. The arm moves in a clockwise direction with a constant angular velocity ω. Assume 0° ≤ Φ ≤ 90°. Neglect any friction. Neglect also the size of the ball and the thickness of the arm. Find the relationship between r, R and θ where r is the distance between O and the ball. Draw a free body diagram of the ball assuming that it is in contact with the cylinder and the arm OA. Write the equations of motion in the (r, θ) coordinate system. Find the normal force acting on the ball by the cylinder for Φ = Φ0. Find the normal force acting on the ball by the bar for Φ = Φ0. Determine the angle Φ at which the ball loses contact with the cylinder.
