n Chapter 5 we look at drag due to air resistance for falling objects. Using the Dv form of dr discussed in class, write a program (or solve analytically) to determine how long (sec.) and how far m) a 150 gram ball whose radius is 3.5cm would fall before it reached 75% of its terminal velocity. Assume ball falls in air whose density is 1.21 kg/m3, has a drag coefficient C .3, cross-sectional area s just the disk a sphere...
An object is dropped from some height above ground. Air resistance on the object is given by Cv, where C = a coefficient of drag in units of N/ (m/s) and v = the object's velocity. Instructions: b)use newton second law and sum the forces on the mass in the y direction. Because v= negative and air resistance opposes motion. you must be careful of signs. Replace acceleration in the equation. d.)Seperate variables... put time on one side of the...
2. Suppose an object of mass 15 kg is dropped from a height near the surface of the Earth, so the acceleration due to gravity is -9.8, and assume the drag due to air 0.47. Assume the object's position is measured in meters above the ground, so velocity (a) Write down, but do not solve, a differential equation whose solution would give resistance is proportional to the square of object's velocity, with drag coefficient γ and acceleration are both negative...
1.A pickup truck is traveling down the highway at a steady speed of 31.1 m/s. The truck has a drag coefficient of 0.45 and a cross-sectional area of the truck is 3.3 3.3 m2. Assume the density of the air is 1.2 1.2 kg/m3. How much energy does the truck lose to air resistance per hour? Give your answer in units of MJ (megajoules). 2.An unknown object is placed inside of a spherical container and dropped from an airplane. When...
A spherical raindrop (r = 0.0015 m) falls from a cloud. The drag coefficient is 0.60. The density of the water is 1000 kg/m^3 and the density of the air it falls through is 1.2 kg/m^3. The shape of the drop doesn’t change during the fall, and the terminal velocity is 7.3 m/s. At this terminal speed, what is the magnitude of the resistive force acting on the drop?
If a dense 20.0-kg object is falling in air at half its terminal velocity (drag force is proportional to the square of the object’s speed), what is the drag force on the object at this moment? a. 25 N b. 50 N c. 75 N d. 100 N e. 150 N
The mass density of air on Mars is ρ=0.016 kg/m3. The gravity on Mars is gMars= 3.7 m/s2. The mass density of air on earth under standard pressure and temperature conditions is ρ=1.225 kg/m3. A NASA mars probe weighs 1000 N on Earth. At terminal velocity, the weight of a falling object is equal to the drag force. Assume that the drag coefficient of the parachute used is constant, and has the same value on both Earth or Mars, and...
In the figure, a long rectangular conducting loop, of width L = 20 cm, resistance R = 11 ohm, and mass m = 0.10 kg, is hung in a horizontal, uniform magnetic field of magnitude 1.3 T that is directed into the page and that exists only above line The loop is then dropped: during its fall, it accelerates until it reaches a certain terminal speed v_ Ignoring air drag, find the terminal speed. Number Units the tolerance is +/-2%
