Physics

A 0.200-kg block on a smooth horizontal surface gains a speed of28.2 cm/s when it is released from rest at the free end of a springthat is compressed by 3.20 cm. The block is then connected to thefree end of the spring to form a mass-spring system.

What is the springconstant? (A) 15.5 N/m; (B)16.5 N/m; (C) 17.5 N/m; (D) 18.5 N/m; (E) 19.5 N/m.

What is the period of this harmonic oscillator? (A) 0.413 s; (B)0.513 s; (C) 0.613 s; (D) 0.713 s; (E) 0.813 s.

What happens to the period if the mass of the block is doubled?(A) No change; (B) Doubled; (C) Increased by 40%; (D) Decreased by40%; (E) Quadrupled.
