Q1. er a) When a mass of 0.05 kg is attached to a vertical spring, it is noticed that the spring's length increases by 3 cm. What is the value of the spring constant k for this spring? b) The mass in (a) is now made to oscillate vertically with simple harmonic motion of amplitude 0.04 m and period 1.25 s i. What is the maximum speed of the mass? ii. What is the maximum force on the mass due to this motion? iii. At the time the mass experiences its lowest acceleration, is its speed a maximum or minimum? Explain. (Correct units must be shown to gain all marks) c) In a rectangular glass prism, light travels a distance of 1.920 m in 8.00 ns. i. What is the index of refraction for the glass in this prism? ii. As the light leaves the prism, it is incident at an angle of 55° to the glass / air boundary. Will the light pass through the boundary or be reflected at the boundary? (You must justify your answer).
