First the amount of work done in lifting up the snow ball to a height of 1.2m is equal to the potential energy of the ball after the lift.
Therefore mass× gravitational pull×height will give us the work done
=3.2kg ×9.8N/kg×1.2m
=37.632J
then, the work done over the 25m distance if found by the following formula: work done=force×distance
=1.0N×25m
=25J
On reaching the headless snowman you have to lift the ball a further 1.1m to place it as the head 2.3m high.
therefore this will be a change in potential energy which is equal to work done in lifting the ball the additional 1.1m
=m×g×h
=3.2kg×9.8N/kg×1.1m
=34.496J
To get the total we add the amount of work done in the various instances.
Hooke's law states that the elongation of a material is proportional to the applied stress within the elastic limits of the material.
Using Hooke's law
F = kx
570 = k * 0.9
k = 712.5 N/m
(a) energy at x = 0.8 m
U = 0.5 k x^2 = 0.5* 712.8* 0.8^2
U = 228 J
(b) U = 0.5 * 712.8* 0.09^2
U = 2.887 J
Elastic potential energy is the potential energy released as a result of the deformation of an elastic body. B. Spring extension is stored. This is equal to the work done to stretch the spring, which depends on the spring constant k and the stretched distance. The force exerted by the spring is the restoring force that helps return the spring to its equilibrium length.
