A 45 grams (0.045 kg) golf ball of diameter equal to 43 mm fell into a 2m deep lake. Neglect inertia at the moment of impact. Assume viscosity of 1.12x10-3 Ns/m2 , water density of 1,000 kg/m3 and Cd=0.5. Sphere volume equals 4π r³ /3. 1. How long will it take from the moment it hits the surface until it gets to the bottom? 2. If one estimates the Cd with Cd=24/Re formula, the settling velocity would be unrealistically large. Why?
A student team is to design a human-powered submarine for a design competition. The overall length of the prototype submarine is 95 (m), and its student designers hope that it can travel fully submerged through water at 0.440 m/s. The water is freshwater (a lake) at T = 15°C. The design team builds a one-fifth scale model to test in their university’s wind tunnel. A shield surrounds the drag balance strut so that the aerodynamic drag of the strut itself does not influence the measured drag. The air in the wind tunnel is at 25°C and at one standard atmosphere pressure. At what air speed do they need to run the wind tunnel in order to achievesimilarity?
Somewhere DEEP BELOW THE EARTH's surface, at an UNKNOWN displacement from the Earth's center, a particle of mass m is dangled from a long string, length L; the particle oscillates along a small arc according to the differential equation d^2x/dt^2=-(pi^2/36)x. Here x refers to an angular displacement measured from the vertical and t refers to time. The particle's mass is given by m=3kg. The length of the string is given by L=5 meters. Whenever the particle arrives at a location of x=(pi/12) radians from the vertical, the particle has no instantaneous speed. On both sides of the vertical, that is, x=(pi/12) radians is repeatedly observed to be a 'turning point' for the particle's periodic motion. 1. Draw a clear FREE-BODY diagram of this particle at some arbitrary point during oscillation, making sure to label variables and constants described above. 2. Approximating to three significant digits if necessary, what is the angular frequency of this oscillator on a string? 3. Approximating…

Using the image on the Moment of Inertia Tab, where the following criteria are considered:Assign the values to “Apply torque” = 2 Nm, “Brake force” fr = 0.2 N. “Platform Mass” m= 0.25 kg.Use"radians" for angle units. Write down the values that appear in the graphs of torque, a moment of inertia, and angular acceleration. Then, obtain the other physical quantities by applying the equations of rotational dynamics that correspond to:Time:4.5Applied torque:2 N-mBrake torque:Net torque:Angular impulse:Moment of inertia:Angular acceleration:Initial angular velocity:Final angular velocity:
This is a dynamics question. Hint: When the man has his arms out, the distance from the CG of his arms to the CM of his body = (0.65/2)+0.2 = 0.525 m. Answer: w2 = 2.55 rev/s
pleassssse solve question 7, statics
A structure has a mass of 10 kip/g and a stiffness of 10 kip/in. The acceleration of gravity, g, is 386.1 in/s2. Provide the period of the structure in seconds.
Dynamics Question A ball with a mass of .5kg is attached to a 1m string. The string is attached to a post and is free to rotate. The string can be assumed to be weightless and not stretch. The ball is spun around the post in the horizontal plane (so gravity is perpendicular to the string and direction of motion) at a rate of 2π radians per second and that is slowing down by .2 rad/s^2. What is the total acceleration vector and the tension in the string?
FLUID STATICS. Only round off in the final answer. Use 3 decimal places. Thank you!Allison places her coffee mug on a spinner and rotates it around its axis. At rest, the mug is 10 cm deep and 6 cm in diameter, and it holds coffee 7 cm deep. What is the maximum angular rotation she can do in rad/s without spilling her coffee?
Hi please help me answer this with drawing, thank you. Plot a displacement diagram for a body that is to rise and fall as follows; rise 1 in. in 4 seconds with uniform acceleration, rise 1 in. in 4 sec. with uniform retardation, rest 6 seconds, fall 1 ¼ in. in 6 sec with harmonic motion, rise ½ in. in 3 sec with uniform velocity, fall 1 ¼ in. at once, and rest 4 sec.. Plot displacement as ordinates full size and the time as abscissas to a scale of 1 in. = 4 sec.
An engineer is to design a human powered submarine for a design competition. The overall length of the prototype submarine is 2.24 m and its engineer designers hope that it can travel fully submerged through water at 0.560 m/s. The water is freshwater (a lake) at 7-15°C (p=999.1 kg/m3 and u= 1.138 ×103 kg/m-st. The design team builds a one-eighth scale model to test in their university's wind tunnel. The air in the wind tunnel is at 25°C (p= 1.180 kg/m3 and u = 1.849 ×10-5 kg/m-s) and at one standard atmosphere pressure. At what air speed do they need to run the wind tunnel in order to achieve similarity?
