Question 1

A spring on a horizontal surface can be stretched and held 0.5 m from its equilibrium position with a force of 45 N. How much work is done in compressing the spring 2.5 m from its equilibrium position?
◦ 56.25 J
◦ 281.25 J
◦ 562.5 J
◦ 112.5 J

Question 2

A heavy-duty shock absorber is compressed 2 cm from its equilibrium position by a mass of 600 kg. How much work is required to compress the shock absorber 5 cm from its equilibrium position? (A mass of 600 kg exerts a force (in N) of 600g, where g ≈ 9.8 m/s².)
◦ 3750 J
◦ 37.5 J
◦ 36,750 J
◦ 367.5 J
