A spherical mass on the end of a string is spinning in a vertical circle about point P. Which of the forces acting on the mass contribute to the "centripetal force" when the mass is in position A? Select all that apply. The tension in the string. The force of gravity (weight). The force of drag (air resistance). Which of the forces acting on the mass contribute to the "centripetal force" when the mass is in position B, directly to...

How does spinning the bob faster affect the period (time required for 1 full revolution)? The period increases. It takes more for the bob to go around once. The period stays the same. The period decreases. It takes less time for the bob to go around once. to the centripetal...

A stone is tied to a string (length L = 1.10 m) and whirled in a circle at the same constant speed in two different ways. First, the circle is horizontal, and the string is nearly parallel to the ground. Next, the circle is vertical. In the vertical case, the maximum tension in the string is 15.0% larger than the tension that exists when the circle is horizontal. step 6: Draw the free-body diagram for the forces acting on the...

A ball with a weight of 2 N is attached to the end of a cord of length 2 m. The ball is whirled in a vertical circle counterclockwise. The tension in the cord at the top of the circle is 7 N and at the bottom it is 15 N. (Do not assume that the speed of the ball is the same at these points.) a) Three students discuss the net forces on the ball at the top: Deante:...

1. A Ferris wheel has a radius of 6 m and makes one revolution in 4seconds (i.e. onerevolution in approximately 12.6 seconds). A person with a mass of 50 kg is sitting on one of thebenches attached to the rim. What is the normal force acting on a the person at the highest pointof the rotating Ferris wheel? Approximate the acceleration due to gravity as 10 m/s2; on a Ferriswheel, the passengers are never upside down. 2. Consider what happens...
In the apparatus shown above, one end of a string of length L is attached to a block of mass M
In the apparatus shown above, one end of a string of length L is
attached to a block of mass M and the other end is connected to the
axle of a motor that rotates, causing the block to move in a circle
of radius R at a constant speed vT such that the string makes an
angle θ with the vertical. A student wants to use the apparatus to
make measurements and create a graph that can be used...

3) A mass of 5 kg is resting on a horizontal, frictionless surface. Force 1 is applied to it at 20 degrees below the horizontal in the -x direction, force 2 has a magnitude of 88 N and is applied in the +x direction , and force 3 has a magnitude of 25 N and is applied vertically downwards. When these forces are applied, the normal force acting on the mass is twice the amount of its weight. Also, when...
