The acceleration of a particle is given by a = -ks2, where a is in meters per second squared, k is a constant, and s is in meters. Determine the velocity of the particle as a function of its position s. Evaluate your expression for s = 7 m if k = 0.4 ms? and the initial conditions at time t = 0 are so = 2 m and vo = 22 m/s. Answer: v = i m/s
