Amass m is tied to an ideal spring with force constant k and rests on a frictionless surface. the mass moves along the x axis. assume that x=0 corresponds to the relaxed position of the spring. the mass is pulled out to a position xm and released. derive an expression for the positions at which the kinetic energy of the mass is equal to the elastic potential energy of the spring.

Explanation:

Given

initially mass is stretched to

Let k be the spring Constant of spring

Therefore Total Mechanical Energy is

Position at which kinetic Energy is equal to Elastic Potential Energy

it is given

thus

according to jean piaget, in what stage of cognitive development are children able to understand conservation task?

b. preoperational

just took it

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
