A rock is suspended from a scale reads 20.0 N. A beaker of water (having a density of 1000 kg/m3) is raised up so the rock is totally submerged in the water. The scale now reads 12.5 N. What is the density of the rock?
A) 1.60 × 103 kg/m3
B) 2.50 × 103 kg/m3
C) 2.33 × 103 kg/m3
D) 3.00 × 103 kg/m3
E) 2.67 × 103 kg/m3

Mass on a Spring: A 4.8-kg block attached to an ideal spring executes simple harmonic motion on a frictionless horizontal surface. At time t = 0.00 s, the block has a displacement of -0.90 m, a velocity of -0.80 m/s, and an acceleration of +2.9 m/s2. The force constant (spring constant) of the spring is closest to
