You are given a drone with an average chord length of 8 in., a wingspan of 2.5 ft, and a weight of 300 g. Based on figure 2, would it stay in the air at a speed of 5 m/s? (Assume ρ=1.225 kg/m3 and Nu=1.516*10-5 m^2/s)

How much energy would it take to raise a can of soda (m = 350 grams) to average cruising altitude (35,000 ft)? Our textbook states that a gallon of gasoline contains 1.2×108 Joules of energy. Assuming 100% efficiency, how many gallons of gasoline would it take to raise the can of soda to 35,000 ft? A calorie is the amount of energy needed to raise the temperature of 1 gram of water by 1 Celsius degree (4.186 J). A nutritional Calorie is actually 1000 calories (1 Cal = 1 kcal). How many Calories of energy does it take to raise the can of soda to cruising altitude?

A car has broken down in the middle of a road. Eva wants to help tow thecar to a mechanic with her 4WD. To avoid the car from slamming into Eva’s 4WD, they attach the front of the car to the back of Eva’s 4WD by a stiff spring.The broken car weighs 2000kg. The spring has a natural unstretched length of 2m and a spring constant of k = 80000N/mFor this particular gravel road, the magnitude of the drag force is proportional to the weight of the car and the speed of the car. The direction of the drag force is always opposite tothe direction of movement. This can be written asD = −cM v For this particular road we can take c = 4. Let x(t) be the position of the front of the broken car and let y(t) be the position of the back of Eva’s 4WD. We will assume that the position of Eva’s car is a known function of time.(1) By considering Newton’s law applied to the broken car, write down an ordinary differential equation for the motion of the broken car They are planning to travel at a constant…
