Aplane is flying horizontally with speed 315m/s at a height 2770m above the ground, when a package is dropped from the plane. the acceleration of gravity is 9.8m/s^2. neglecting air resistance, when the package hits the ground, the plane will be.1) behind the package.
2) ahead of the package.
3) directly above the package.

3) directly above the package.

Step-by-step explanation:

The plane and the package carried by the plane are traveling with the same horizontal speed. When the package is dropped, a new vertical component of velocity is added to the package. The vertical velocity increases because of the acceleration due to gravity. The horizontal speed of the package remains the same. As long as the plane continues to fly at the same speed, the package hits the ground directly below the plane.

3) directly above the package.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
