The student will feel light. The centrifugal force acts on the student radially outwards when the Ferris wheel spins. At the highest point, this force acts against the weight, hence the student will feel light c. At the highest point, this force acts against the weight, reducing it from 667N to 556 N, So it has magnitude of 667-556=111 N This will act downwards at the lowest point, adding to the weight at the lowest point, So W= 667+ 111 = 776 N d. centrifugal force = mv^2 / r, doubling the velocity will make us have 2^2 = 4 times Hence we will have 4 times centripetal force Maginute = 111*4 = 444 N ...Download file to see next pagesRead More
