A1.00-kg mass vibrating up and down on the end of a vertical spring has a maximum speed of 2.60 m/s. what is the total potential energy of the mass on the spring when the mass is at either endpoint of its motion? note: assume that the potential energy of the mass on the vertical spring is zero when the mass is at the midpoint of its motion. give your answer in joules.

3.38 J

Explanation:

Given

mass of vibrating Particle

Maximum speed of mass is

It is given that Potential Energy of the mass is zero when the mass is at mid point that considering the mid point as datum

So kinetic energy is maximum at mid point while Potential energy is maximum  at end points .

As energy is conserved therefore

Total Kinetic Energy at midpoint =Total Potential Energy at Either end points

it would be kevlar ^^

i think its c if i'm wrong
