Work is done when spring is extended or compressed. Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.
Answer:
Corpuscular theory of light
Explanation:
In optics, the corpuscular theory of light, arguably set forward by Descartes in 1637, states that light is made up of small discrete particles called "corpuscles" which travel in a straight line with a finite velocity and possess impetus. This was based on an alternate description of atomism of the time period.
They have thick body coverings
Answer:
7.53 m
Explanation:
Force, F = 47 N
initial velocity, u = 0
Final kinetic energy, Kf = 354 J
Let the distance traveled by the student is s.
According to the work energy theorem,
Work done by all forces = Change in kinetic energy
Force x distance = final kinetic energy - initial kinetic energy
F x s = kf - ki
47 x s = 354
s = 7.53 m
