Academics

Q1. A piece of rock weighs 298 N in air and has an apparent weight of 214 N when suspended in water.

a. What is the volume of rock?

b. What is the density of rock?

Q2. Small steel ball bearing with a mass of 17 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.39m. Calculate the horizontal distance ball would travel if the same spring were aimed 39 deg from the horizontal.
