A raindrop of mass 0.5 * 10^-4 kg is falling verctically under the influence of gravity. The air drag on the raindrop is fdrag = 0.2 * 10^-5 v^2, where v is the speed of the raindrop. Find the displacement of the ain drop after 3 second, assume the raindrops starts from rest and use 10m/s^2 for the acceleration of gravity

An object with a mass of 10.0 kg is falling under the effect of gravity near the earth's surface with negligible air resistance. There is a force of 55 N pushing it to the left (you can pretend that this force is due to wind if that helps). What is the magnitude and direction of the total force felt by the object? Note: if the magnitude is greater than 140 N then you have done this problem wrong and you...

A mass of 0.5 kg is attached to a spring whose k=8000 N/m. The system rests on a level friction-free air track and is initially at rest. A second mass makes a head-on elastic collision with the mass attached to the spring; thereafter the oscillating system vibrates with amplitude of 0.5 m. If the incident mass is 0.4 kg, what was its incident speed?

A solid cylinder of radius 0.5 m and mass 5.0 kg, initially at rest, starts to rotate about an axis through its center, with an angular acceleration of 0.2 rad/s^2. (a) Assuming a piece of string is wrapped around the cylinder, in such a way that the turning cylinder pulls the string onto itself, what is the total length of string wrapped on the cylinder at t= 10s? (b) What is the linear acceleration of a knot in the string...

An object of mass 120 kg is released from rest 480000 m above the ground and allowed to fall under the influence of gravity. Assume the gravitational force is constant, with g=9.8 m/sec2 , and the force due to air resistance is proportional to the velocity of the object with proportionality constant k= 3 kg/sec. Approximate the speed (in m/sec) of the object when it strikes the ground.

An eagle is circling looking for prey, it completes a circle of radius 10 m every 5 s. Birds can use their skills to make air exert a force on them in any direction. a) Draw a diagrams of the eagle’s motion, indicate the velocity vector and the coordinate system. b) What are the linear and angular speed of the eagle? c) If the eagle increases its speed over thirty seconds, to complete one circle (r=10m) every 3s, calculate the...

A m=5 kg mass hangs on a spring that is stretched 2 cm under the influence of the weight of this mass. The mass is attached to a damper with a damping constant of c=200 Ns/m. A periodic external force of F(t) = 200cos(ωt) is now applied on the mass that was initially in static equilibrium. Neglecting any friction, obtain a relation for the displacement of the mass x(t) as a function of ω and t. Also, determine the value...

A solution of density 1100 kgm^-3 and viscosity 2×10^-3 Pa s is flowing under gravity at a rate of 0.24 kg/s through a bed of catalyst particles. The bed diameter is 0.2 m and the depth is 0.5 m. The particles are cylindrical, with a diameter of 1mm and length of 2 mm. They are loosely packed to give a voidage of 0.3. Calculate the depth of liquid above the top of the bed.

A string is attached to the rim of a small hoop of radius r = 8.00×10−2 m and mass m = 0.180 kg and then wrapped several times around the rim. If the free end of the string is held in place and the hoop is released from rest and allowed to drop, as shown in the figure (Figure 1), calculate the angular speed and the translational speed of the rotating hoop after it has descended h = 0.750 m...

A rocket has total mass ??I= 4 × 105 kg at the time of ignition; 95% of this mass is fuel. After ignition, gas is ejected at a constant rate of 1200 kg/s with an ejection speed of 3 × 103 m/s. The rocket is launched vertically from the surface of the earth. Ignore air drag and assume gravity is constant when answering the following. a) (2 points) How long after ignition does the rocket lift off and how much...
