You hold a bucket in one hand. in the bucket is a 500g rock. you swing the bucket so that the rock moves in a vertical circle 2.2m in diameter. what is the minimum speed the rock must have at the top of the circle if it is to always stay in contact with the bottom of the bucket?

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
