What is the acceleration?

\overline {a} = {v - v_0}{t} = \frac{\Delta v}{\Delta t}

\overline{a}=average acceleration

v=final velocity

v_0=starting velocity

t=elapsed time

Explanation: math i hoped it helped.

b would be the answer

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
