A object-spring system oscillates with an amplitude of 2.8 cm. If the spring constant is 205 N/m and object has a mass of 0.50 kg, determine each of the following values.
(a) the mechanical energy of the system.
(b) the maximum speed of the object.
(c) the maximum acceleration of the object.
If I end up with a velocity of 1 m/s going west, am I heaver or lighter than you? What is your mass, and what is your final velocity?
Through what maximum angle θmax will the reference line turn in the positive direction? What are (b) first and (c) second times the reference line will be at θ = θmax/3? At what (d) negative time and (e) positive time will the reference line be at..
