A rock, which weighs 1400 N in air, is dropped into fresh water (998 kg/m3). You measure that it accelerates downward at a rate of 6.25 m/s2. What is the volume of the rock?
Homework Answers
net firce acting on rock
ma = W - F
(1400/9.8} * 6.25 = 1400 - 1000* V * 9.8
V = 0.0517 m^3
==========
comment before rate in case any doubt, will reply for sure.. goodluck

To verify her suspicion that a rock specimen is hollow, a geologist weighs the specimen in air and in water. She finds that the specimen weighs twice as much in air as it does in water. The density of the solid part of the specimen is 2.49 × 103 kg/m3. What fraction of the specimen’s apparent volume is solid?
