A small block with mass 0.210 kg is attached to a string passing through a hole in a frictionless, horizontal surface (Figure 1). The block is originally revolving in a circle with a radius of 0.800 m about the hole with a tangential speed of 4.00 m/s. The string is then pulled slowly from below, shortening the radius of the circle in which the block revolves. The breaking strength of the string is 30.0 N. Part A What is the radius of the circle when the string breaks? Express your answer with the appropriate units. - Value Units

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.
1a. Several objects have the same mass and radius and are placed at the top of a hill of height ℎ. If all the objects are released from the same height ℎ at the same time, rank the order in which the objects reach the bottom of the hill, from first to last. The moment of inertia of each of the objects are listed below. If any of the objects tie, indicate that in your ranking. Object 1: Hoop Object 2: Solid Sphere Object 3: Disk Object 4: Hollow Object 5: Solid Cylinder Ihoop = MR2 Isolid sphere = (2/5)MR2 Idisk = (1/2)MR2 Ihollow = (2/3)MR2 Isolid cylinder = (1/2)MR2
The sphere at A is given a downward velocity v0 and swings in a vertical circle of radius I and center O. Determine the smallest velocity v0 for which the sphere will reach point B as it swings about point O (a) if AO is a rope, (b) if AO is a slender rod of negligible mass.
Hello, I need help with physics. Thank you!Consider a circle-circle collision, where both circles are identical and are able to move. The coefficient of resititution is 0.842. Ball A has an initial velocity of (0.08, 6.54) px/s and is centred at pixel position (4.02, -7.56) at the moment of impact. Ball B is stationary and is centred at pixel position (0.9, -0.71) at the moment of impact. Calculate the magnitude of the change in velocity along the normal for ball A or B (ignoring friction). Note that this is just a number, not a vector. Leave your answer accurate to 2 decimal places.
A completely smooth table has a circular end with radius R=40.0 cm. The height of the table is h= 1.00 m. A body is thrown on the table and it is desired that the body does not slide down the circular part, but at the point where the circular part begins, said body falls off. Complying with the above, find the distance where the body falls with respect to the table (g=9.8 m/s2). If you think that information is missing, you can assume it.
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?

Must answer all the four questions. Otherwise dont attempt it.i will dislike. A yoyo composed of an axle of diameter 1cm, is connected to two disks of diameter 6.5cm, and falls from rest. The string looped around the axle unwinds as it falls, and the body of the yoyo spins in a clockwise direction about its centre of mass with a tangential acceleration of 2 m/s2. a) Derive the equation for the tangential velocity v in terms of time t. b) Calculate the rotational acceleration of the yoyo to 3 significant figures. Indicate the direction as either clockwiseor anticlockwise. c) Derive the equation for the rotational velocity ω in terms of time t given that the initial velocity is 0.5 rad/s. d) Calculate the total angular displacement the yoyo travels given that the yoyo string is 5m long.
Problem: A swing consists of a board at the end of a 15 feet long rope. Think of the board as a point P at the end of the rope, and let Q be the point of attachment at the other end. Suppose that the swing is directly below Q at time ? = 0, and is being pushed by someone who walks at 6 ft/sec from left to right. i) How fast the swing is rising after 1 second. ii) Find the angular speed of the rope in deg/sec after 1 second.
Riders in an amusement park ride shaped like a Viking ship hung from a large pivot are rotated back and forth like a rigid pendulum. Sometime near the middle of the ride, the ship is momentarily motionless at the top of its circular arc. The ship then swings down under the influence of gravity. (a) Assuming negligible friction, find the speed (in m/s) of the riders at the bottom of its arc, given the system's center of mass travels in an arc having a radius of 16.0 m and the riders are near the center of mass. (Assume the top of the circular arc is when the pendulum arm is horizontal. You may need to use energy methods from the next chapter.) (b) What is the centripetal acceleration (in m/s2) at the bottom of the arc?
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.
