1. Santa is cruising in the air in his sled. His reindeer are pushing full steam ahead with 8,000 N of force. Santa and his sled are encountering 4000 N of air resistance (he’s a big guy) and the total weight of Santa, sled, reindeer and toys is 1000 Kg.

a) Draw a freebody diagram using the scale 1cm = 1000 N on the diagram below. Label all vectors

b) Determine the net force in the x-direction

c) Is Santa accelerating? Show your work.

d) What is 1 Newton equal to? Use Newton’s Second Law in your answer.

2. Santa’s reindeer are tired so he decides to jump out of a plane with his bag of presents. Santa is accelerating for the first part of the jump at 9.81 m/s2 due to no air resistance (he magically turned it off). If Santa has a mass with toys of 300 Kg, find:

Show all work in your answers including equation and substitution with units.

a) Draw a freebody diagram using the scale 1cm = 500N on the diagram below. Label all vectors.

b) What is the net force in the y direction?

c) Santa accidentally hits the button to turn off air friction and slows down to a constant speed as he falls. How much air friction is he encountering if it causes him to stop accelerating?

d) Draw these vectors on the freebody diagram using a red colored pencil.

3. Rudolph the Red Nosed reindeer is running to help Santa. If he is running with a net force of 500 N and is accelerating at 3.1 m/s2, determine Rudy’s mass in kilograms.

b) What is Rudy’s weight in lbs? (use 1 kg = 2.205 lbs)

Thanks for the help. And yes, this is high school physics. In February.

For his engineering project, Fran¸cois built a model rocket of mass m = 0.55 kg simply by using materials he found lying around the lab and blueprints he found on the internet. The rocket’s propulsion is provided by a special battery-powered fan that is able to provide a constant force |Ffan| = 7.0 N – that is, once it is launched in a specific direction, the direction of the fan’s force does not change. The downside is that the rocket...

Design a "bungee jump" apparatus for adults. A bungee jumper falls from a high platform with two elastic cords tied to the ankles. The jumper falls freely for a while, with the cords slack. Then the jumper falls an additional distance with the cords increasingly tense. Assume that you have cords that are 12 m long, and that the cords stretch in the jump an additional 19 m for a jumper whose mass is 120 kg, the heaviest adult you...
