Help me with my homework. 1. A person from the top of a tree drops a stone, another person from the ground takes time in that takes time to fall the stone and realizes that there are 3 Seconds. Calculate the speed with which the stone impacts the ground and the height of the tree. Take into account that gravity is 9.8 m/s²

2. A child kicks a soccer ball up, it will give him

prints a speed of 30 m/s, if upon reaching its height

maximum its final speed is zero and it takes 4

seconds to reach it, what is the maximum height that

Reached.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

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 .

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
