A 30-kg child rides on a circus Ferris wheel that takes her around a vertical circular path with a radius of 20m every 22s. What is the magnitude of the resultant force on the child at the highest point on this trajectory

answer; i believe that the correct answer is (d) a very small amount of mass

b

explanation:

it becomes positively charged by charging it

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
