QUESTION 1

On aircraft carriers, catapults are used to accelerate jet aircraft to flight speeds in short distances. If a force of 600,000 N acts on a Boeing F-15 Eagle Tactical Fighter, accelerating it from 0 to 85 m/s in 3.2 seconds, what is the weight of the jet in kilograms

QUESTION 2

A man has a weight of 800 N on Earth. What is the man’s weight on Mars if g = 0.39?

QUESTION 3

A 0.25 kg ball is attached to string and whirled around in a circle. The string breaks if the force exceeds 50 N. What is the acceleration of the ball if the force is 50N?

QUESTION 4

Mass and weight of objects are not the same. If a child mass is 75 pounds, what is the child’s weight in Newtons?

QUESTION 5

A centripetal force of 150 N acts on an 800 kg satellite moving with a speed of 4,500 m/s in a circular orbit around a planet. What is the acceleration of the satellite in m/s2?

QUESTION 6

An airplane has a mass of 4,800 pounds. If a force of 130,000 N is applied, what is the acceleration is g’s?

QUESTION 7

Static friction opposes gravity, which acts to pull a wood block down an inclined plane. What is the total value of the gravitational force (Fg) and the force due to friction (Ff) in Newtons if the wood block is sitting on a flat surface?

QUESTION 8

The weight of a bear is 3,200 N. What is the bear’s weight in kilograms (kg)?

QUESTION 9

In an experiment performed in a space station, a force of 80 N causes an object to have an acceleration of 6.3 m/s2. What is the object’s mass in kilograms (kg)?

QUESTION 10
