Lesson Worksheet: Newton’s First Law of Motion Mathematics
In this worksheet, we will practice solving problems using Newton’s first law.
An engine pulls its carriages along a horizontal track at uniform speed. Given that the engine provides a driving force of 2,080 kg-wt and combined mass of the engine and carriages is 250 metric tons, determine the resistance to their motion per tonne.
A soldier jumped out of a plane with a parachute. After he had opened his parachute, the resistance to his movement was directly proportional to the cube of his speed. When his speed was 19 km/h, the resistance to his motion was of the combined weight of him and his parachute. Determine the maximum speed of his descent.
