applying conservation of energy 1/2 mg/a x2 + K.E = mgx .............(1) (spring energy) (of block) (of block)
where x is the elongation of the spring at equilibrium position now at equilibrium position mg/a x= mg (spring force) (wt of block) therefore x=a substitute in above eqn1 we get K.E=mga/2
plzzzzz rate me if i am correct
FAILURE IS NOT FALLING IN LIFE BUT NOT RISING AGAIN AFTER FALLING!!!!!!
I LIKE WAVES NOT BECAUSE THEY RISE AND FALL..
BUT BECAUSE EVERYTIME THEY FALL THEY RISE AGAIN!!!!!!!
