Explanation / Answer

Here,

m = 0.014 Kg

k = 1.15 N/m

a) let the maximum velocity is v

Using conservation of energy

0.50 * 0.014 * v^2 = 0.50 * 1.15 * 0.0335^2

solving for v

v = 0.304 m/s

the maximum speed of the object is 0.304 m/s

b)

kinetic energy of the object = 0.50 * m * v^2

kinetic energy of the object = 0.50 * 0.014 * 0.304^2

kinetic energy of the object = 6.45 *10^-4 J
