The force required to stretch a hooke’s-law spring varies from 0 n to 43.2 n as we stretch the spring by moving one end 14.4 cm from its unstressed position. find the force constant of the spring. answer in units of n/m.

Spring constant = 300 N/m

Explanation:

For a spring we have force is the product of spring constant and displacement.

          Force = Spring constant x Displacement

          F = k x

Here Force , F = 43.2 - 0 = 43.2 N

         Displacement, x = 14.4 cm = 0.144 m

Substituting

              F = k x

              43.2 = k x 0.144

               k= 300 N/m

Spring constant = 300 N/m

the closer the planet is to the sun, the larger the gravity

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
