Since we answer only 3 subparts, we will answer 1st three. please resubmit the question and specify the other subparts The ball of mass m shall complete the circle if the string does not slack or the tension in the string should not be 0 even when the ball reaches the top of the circular path. The ball in the image follows this equation, T is the tension in the string and R is the radius of the circle( also the length of the circle) T-mg cosθ=mv2R (1)θ=π at the highest point, T+mg=mv2RT=mv2R-mg Answer : a) tension should be greater than or equal to zero to just loop the highest point, T=0N for just to circle the loop putting θ=π and T=0N, putting this in equation 1 mg=mv2minRv2min=Rgvmin=Rg =9.8×1 =3.13 m/s Answer b: the minimum speed at the top is 3.13m/s To just ensure a circular loop vmin=Rgu2min=v2min+2ghh=2R at the topu2min=Rg+4Rg =5Rgumin=5Rg =5×9.8m/s =7m/s Answer c: the minimum initial velocity required=7m/s

A roller coaster cart is released at the top of a frictionless track at the point A (see Figure below). Find its initial height above the ground, h, if the apparent weight (equal the magnitude of the normal force) of a person, when the cart goes on top of a circular hill of the radius R=12.0 m at B, is 30% of the normal weight. The initial speed of the cart is zero.
A 900 g ball moves in a vertical circle on a 1.03 m long string. If the speed at the top is 4.10 m/s, then the speed at the bottom will be 7.56 m/s. What is the tension in the string when the ball is at the top and when it is at the bottom? Can you please provide a detailed solution as I must learn this topic by myself and it is quite confusing/difficult. Thank you :)
Largely because of riding in cars, you are used to horizontal circular motion. Vertical circular motion would be a novelty. In this sample problem, such motion seems to defy the gravitational force. In a 1901 circus performance, Allo “Dare Devil” Diavolo introduced the stunt of riding a bicycle in a loopthe- loop Assuming that the loop is a circle with radius R= 2.7 m, what is the least speed v that Diavolo and his bicycle could have at the top of the loop to remain in contact with it there?
