3. A0.1 kg mass is attached to a spring (k- 0.4 Nm) and oscillates with an amplitude d and period T as illustrated. Let d - 0.5 m and T- 3.1 second. Spring Tew (a) Find the velocity v of the mass at time 3/4 T. (b) Find the acceleration a of the mass at time 3/4 T. (e) How far has the mass traveled at that point?

(a) Find the velocity v of the mass at time 3/4 T.
(b) Find the acceleration a of the mass at time 3/4T.
(e) How far has the mass traveled at that point?
(4) The mass is now doubled, and the spring's length is doubled, while d keeps constant. (An identical
spring is attached to one end.) Solve part (b) for this new situation.
(e) The double mass has a second, identical spring placed beside the first spring, while d keeps constant;
solve part (b) again for this situation.
