Jogger A has a mass m and a speed v, jogger B has a mass m/2 and a speed 3v, jogger C has a mass 3m and a speed v/2, and jogger D has a mass 4m and a speed v/2. Rank the joggers in order of increasing kinetic energy. Indicate ties when appropriate. Show your work.

B>A=D>C

Explanation:

Kinetic Energy is the product of mass and square of the velocity

For Jogger A

For Jogger B

For Jogger C

For Jogger D

Kinetic Energy of Joggers in increasing order

B>A=D>C

c. rb

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

find the surface area of the sphere to the nearest square unit. use a calculator.
