Full explan please 3. A0.1 kg mass is attached to a spring (k- 0.4 Nim) and oscillates with an amplitude d and period T asillustrated. Let d = 0.5 m and T= 3.1 second.SpringTene(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 identicalspring 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.

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