Mass and Weight with Applications Worksheet Mass and Weight with Applications Worksheet 1) Knowing that 1 lb = 4.448 N, find: A) Your weight in Newtons. B) Your mass in Kilograms. 1) Knowing that 1 lb = 4.448 N, find: A) Your weight in Newtons. B) Your mass in Kilograms. 2) The mass of your new motorcycle is 250 kg. What is: A) Its weight on Earth? B) Its Weight on the moon where g = (1/6)gearth? C) The mass of your motorcycle on the moon? 2) The mass of your new motorcycle is 250 kg. What is: A) Its weight on Earth? B) Its Weight on the moon where g = (1/6)gearth? C) The mass of your motorcycle on the moon? 3) Somewhere you place a 7.5 kg pumpkin on a spring scale. If the scale reads 78.4 N, what is the acceleration due to gravity (g) at that location? 3) Somewhere you place a 7.5 kg pumpkin on a spring scale. If the scale reads 78.4 N, what is the acceleration due to gravity (g) at that location? 4) With her parachute open, a 45 kg skydiver falls toward the Earth at a constant velocity of 10 m/s. A) What is the weight of the skydiver? B) What is the magnitude and direction of the drag force from the parachute on the skydiver? 4) With her parachute open, a 45 kg skydiver falls toward the Earth at a constant velocity of 10 m/s. A) What is the weight of the skydiver? B) What is the magnitude and direction of the drag force from the parachute on the skydiver? 5) A 50 kg person has decided to try bungee jumping. Three seconds after she has stepped off of the platform, she has a downward acceleration of 8 m/s/s – the cord is still slack at this point. A) Why is her acceleration not -9.8 m/s/s? B) What is the size and direction of the net force on the bungee jumper? C) What is the bungee jumper’s weight? D) What is the magnitude and direction of the other force, contributing to the net force, acting on her? 5) A 50 kg person has decided to try bungee jumping.
