Grey decides to take his jet ski out for a spin. He first skis 6 meters south and then turns west and skis 8 meters. What is Grey's distance from the dock? What is his displacement from the dock? Make sure to show all your work and provide proper units and direction. Finally, determine which measurement is a vector quantity and which is a scalar quantity.

Physics

$\Delta x = 0.073 m$

Explanation:

Potential energy of the spring is given by the formula

$U = \frac{1}{2}kx^2$

so here we can say that the potential energy stored in the spring is directly depends upon the square of the deformation of the spring

So here we can say that

U = 1 J

x = 0.1 m

so we have

$1 J = \frac{1}{2}k(0.1)^2$

k = 200 N/m

now if we have to increase the potential energy to triple of this initial value

then we have

U = 3.0 J

so we will have

$3.0 = \frac{1}{2}(200) x^2$

x = 0.173 m

so we have to further compress the spring by

$\Delta x = 0.173 - 0.10$

$\Delta x = 0.073 m$
