Question1

A small steel ball bearing with a mass of 30.0 g is on a short compressed spring. While aimed vertically and suddenly released, spring sends the bearing to a height of 1.33 m. compute the horizontal distance the ball would travel if the similar spring were aimed 34.0o from the horizontal.

Question2

A 205 rad dose of radiation is administered to a patient in an attempt to combat a cancerous growth. Assuming all of energy deposited is absorbed by the growth, analyse the amount of energy delivered per kg.

Question3

A force of 310 N is applied horizontally to a crate in order to displace the crate 45.0 m across a level floor at a constant velocity. As a result of this work, crate's inner energy is increased by an amount equal to 12 percent of the crate's initial internal energy. Compute initial internal energy of crate.
