2. Let t be the time of travelling 20 cm at uniform motion, k the spring constant, d the distance 20 cm; and x the spring stretch. Using conservation of energy concepts, show that the equation of t as a function of x is: (4 marks, T) t = ((1%))? [1] 3. Perform a dimensional analysis for the above equation. (2 marks, A) 4.
