A pig is hanging from a string and moving in a horizontal (conical) circle. A. Describe which forces balance which other forces in this scenario and explain why. B. If the string is one meter long and the pig is making a 0.15 m radius circle, what angle is between the circle and the string? C. If the pig has a mass of 0.25 kg, what is the tension in the string? D. How fast must he be travelling for this system to be stable?

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.

4. A Ferris wheel has a radius of 9.00 m and is set so that its passengers move at 3.00 m/s. The mass of a passenger is 60 kg. a. What is the passenger's normal force when the Ferris wheel is at the bottom of its path? b. What is the force factor at the bottom? c. What is the passenger's normal force at the top? d. What is the force factor at the top?

Starting from rest, a 150 kg body experiences a force of 100 newtons acting on it in a direction parallel to the positive x-axis and a force of 150 newtons acting at 55° with respect to the positive x-axis. a. What is the net force acting on the body?  Include direction. b. What is the acceleration of the body? c. What velocity does it reach after 5 seconds?

A ball on a string moves around a complete circle, once a second, on a frictionless, horizontal table. The tension in the string is measured to be 6.0 N. What would the tension be if the ball went around in only half a second? A. 1.5 N B. 3.0 N C. 12 N D. 24 N

The coefficient of kinetic friction is equal to the force of kinetic friction divided by   a. the normal force b. the weight of the object c. the mass of the object d. the acceleration of the object     Why is static friction more complex in analysis than kinetic friction? a .Because its magnitude and direction can vary b. Because it is invisible c. Because it does not depend on the normal force d. Because it depends on the kinetic friction

Migo exerts a horizontal force on a 2 kg box located on an inclined plane with an angle of θ= 37 degrees. The coefficient of static and kinetic friction between the box with an inclined plane is μs = 0.4 and μk = 0.2, respectively. A. What is the minimum force for the box to move exactly B. What is the maximum force for the box to move exactly C. If the box is falling at an acceleration of 0.5 m/s^2, what is the force applied

In the image is a stopper attached to a fishing line that is threaded theough a glass rod. Hanging from the end of the line opposite the stopper is a 100-gram mass. The stopper is being whirled in a horizontal circle, first quickly, then decreasing to a slower speed. a. Is the string pulling inward on the stopper? b. Is there a force pulling the stopper outward? c. True or false: The inward force and outward forces balance, and since the speed is constant, there's no acceleration and there is equilibrium.

A 60 kg student rides on a roller coaster that makes a vertical loop. a. Draw a free-body diagram for when the student is at the bottom of the loop. B.if the radius of the loop is 30m,and the roller coaster is traveling at 20 m/s at the bottom of the loop,what is the net force acting on the student in the vertical direction? C.What force does the seat apply to the student when at the bottom of the loop?
