Problem 2: A 165 lb skydiver jumps off from a plane at a height 10,000 ft. In the first 30 seconds, the drag force due to air resistance is 2v. Use g = 32 ft/s'. (A) What is the differential equation (as an explicit derivative) that describes the motion of the skydiver? (B) what is the velocity of the skydiver after the first 10 seconds? (C) What is his altitude at that instant of time? After the first 30 seconds, the parachute is released to increase the drag force. If this time, the drag force is proportional to the square of the velocity, (D) find an expression for the velocity at any time t after the initial 30 seconds, assuming the same value of k. It's alright if your answer is in implicit form.

Remember that the acceleration due to gravity near the earth's surface is 32 ft/sec2. gamma=?sec-1 Next find the distance D fallen in 10 seconds. D=?ft
A pilot flew his single-engine airplane 60 miles with the wind from City A to above City B. He then turned around and flew back to City A against the wind. If the wind was a constant 20 miles per hour, and the total time going and returning was 1.3 hours, find the speed of the plane in still air.
An object is dropped from a 100 ft building. If the air resistance density (p=k/m) is 0.1, determine the velocity of the object 4 seconds after it falls. Use g= 32 ft/s².
The head injury criterion (HIC) is used to assess the likelihood of head injuries arising from various types of collisions; an HIC greater than about 1000 s is likely to result in severe injuries or even death. The criterion can be written as HIC = (aavg/g)2.5Δt, where aavg is the average acceleration during the time Δt that the head is being accelerated, and g is the free-fall acceleration. Shown is a simplified graph of the net force on a crash dummy’s 4.5 kg head as it hits the airbag during a automobile collision. What is the HIC in this collision?
The model for this set of velocity data is given by: v(t) = [(1100/3)e^(-0.03t)] - (462/5) Use this model to calculate the instantaneous acceleration at t = 15, t = 25, t = 35, and t = 45 seconds. Use this model to calculate the total distance traveled at t = 15, t = 25, t = 35, and t = 45 seconds.
A man flies a small airplane from Fargo to Bismarck, North Dakota a distance of 180 miles. Because he is flying into --- a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1 hour 12 minutes. What is his speed in still air, and how fast is the wind blowing? Your answer is his speed equals the wind speed equals
