2. An object of mass 6.0 kg is whirled around in a vertical circle on the end of a 1.0 m long string with a constant speed of 8.0 m/s. Include a free-body diagram for each of the following questions and explain neatly in detail. a. Determine the maximum tension in the string, indicating the position of the object at the time the maximum tension is achieved. b. What is the minimum speed the object could be rotated with and maintain a circular path? c. If the object is rotated with the same speed (8.0 m/s) on a horizontal surface, what is the tension in the string if the string is parallel to the surface?

Activity No. 2: The Wonder of Circular Motion 1. Prepare the materials: smooth floor, marble, and roll of masking tape. (You can use alternative objects if they are not available at home as long as they have similarities in form.) 2. Clear out a wide patch of floor. 3. Place the marble inside the roll of tape. 4. Grip the outside edge of the roll of tape with the fingers of one hand. Spin the tape in a circular motion on the floor, not lifting it off the ground. The marble should start going around in a circle. 5. Now, lift the roll of tape and see how the marble travels. 6. Repeat several times.

A 1500kg car travels around a circular track at constant speed

Your brother’s toy car has a mass 0f 250. g. The car is going in a vertical circle in 3.50 s. The radius of the track is 40.0 cm. a. Draw Free Body Diagram of the car when it is at the bottom of the circle. b What is the magnitude of the force of the track on the car at the lowest point of the circle?     a. Draw Free Body Diagram of the car when it is at the bottom of the circle.

U3 - CIRCULAR MOTION AND ORBITS PROBLEM SET 3. A car of massm = 1300 kg traveling at 55.0 km/hour enters a banked turn covered with ice. The road is banked at an angle 0, and there is no friction between the road and the car's tires. Use g = - 9.80 m/s? throughout this problem. What is the radius r of the turn if e = 20.0° (assuming the car continues in uniform circular motion around the turn)?

A. A 1800 kg car's tires have a coefficient of friction equal to 0.25 on wet asphalt. What is the fastest that this car can drive along a flat turn with a radius of 200 m without slipping? B. How would this speed change if the car had a mass of 3600 kg instead? C. How would this speed change if the road were slanted? Would the possible speed be higher or lower?

38. A ball on the end of a rope is rotating in a horizontal circular path. Which force maintains this circular motion?A. the force of gravity aloneB. the tension of the rope aloneC. the vertical component of the tension of the rope and gravityD. the horizontal component of the tension in the rope and gravity

An intergalactic spaceship arrives at a distant planet that rotates on its axis with a period of T = 31 hours. The mass of the planet is M = 2.1 • 1025 kg. The spaceship enters a circular orbit with an orbital period that is equal to the planet's period for the rotation about its axis, T.   a.  Enter an expression for the radius of the spaceship’s orbit.  b.  Calculate the orbital radius in meters.

Only do b and c.
