Explanation / Answer

18 oscillations in 16 sec

=> time period of oscillation ,T = 16/18 = 0.888 sec

a) spring force = weight of the ball

=> kx = mg

=> 14*0.02 = m*9.8

=> mass of the ball = 28.57 gram = 0.0285 kg

b) maximum speed will be at mean position

=> 0.5*k*x^2 = 0.5*m*v^2

=> 14*(0.02)^2 = 0.0285*v^2

=> v = 0.443 m/s max speed.
