As an approximation, assume a radialdistance of 85 cm between the branch and the point where the monkey'smass is located. As the monkey swings through the lowest point on thecircle, it has a speed of 2.8 m/s. Find (a) the magnitude of the centripetalforce acting on the monkey and (b) the magnitude of the tension in themonkey's arm.

And don't worry about whether the passengers would actually survive the trip. They are lightweight crash test dummies. NTC A cart of mass m= 347 kg is going around a circular loop-the-loop. There is no motor. The cart moves only under the influence of gravity. Ignore friction and let g = 9.81 meters per second squared. The loop has a radius of r meters. When the cart is at the top of the loop, the normal force on the cart (exerted by the track) pushes down on the cart with a force of N = 1,330 newtons. When it is at the bottom of the loop, the cart has a speed of 30.7 meters per second. What is the radius of the loop (in units of meters)?

The incline has a coefficient of kinetic friction of .12, is 1.25 m long, and has a final change in elevation of .35m. Does the ball reach the top of the incline? If so, where does the ball land? If not, what is the velocity of the ball as it rolls off the bottom of the incline? 25kg 1.25m .35m

In the game of tetherball, a ball is hung from a vertical pole via a 0.75m rope. The rope is allowed to pivot freely from the top of the pole so the ball can swing around the pole. If the angle of the rope is 30° with respect to the pole, how much time does it take the ball to make one complete revolution around the pole?

the speed of the roller coaster, in meters per second, is 16.71. At the top of the loop if the radius of curvature is 15 m the downward acceleration of the car is 1.9g. The height of the loop is 14.15 m. If the loop actually starts 6.5 m higher than your answer to the previous part (yet still reaches the top of the loop with the same velocity), how much energy, in joules, did it lose to friction? Its mass is 1400 kg.

An object with mass M slides across a frictionless half-circular slide of radius R. The object is initially held stationary at the top of the slide. The initial height is, hi = R. The mass is released and slides down, around the bottom, and back up the other side. The radius of the slide is R = 5.79 m and the mass of the object is M = 37 kg. When the object is moving up the slide, at an angle θ = 18o from the vertical, what is the normal force on the object?
