The potential energy of a particle of mass m free to move along x-axis is given by U =/2 kx for
x<0 and U=0 for x 20 (x denotes the x-coordinate of the particle and k is a positive constant). If total mechanical energy of the particle is E, then its speed at x = (plz check out the attachment)



​

Answer 1

Answer:

zero

Explanation:

because x=√2e/k mechanical energy is E. E = sum of kinetic energy and potential energy
