Many birds can attain very high speeds when diving. The mass of a diving swallow is estimated to be 0.018 kg, its drag coefficient is 0.12, and its cross-section area as 5.6×10−4m2.
What is the terminal velocity for this swallow as it dives?

At very low speeds, the resistance to motion offered by a liquid or gas is nearly proportional to velocity; such a viscous drag force opposes the motion and can be writ- ten fviscous = −bv, where the constant of proportionality is known as the viscous drag coefficient. A tiny spherical metal particle of mass 6 × 10−6 g (neglect buoyancy ef- fects) falling though oil has a drag coefficient b = 3 × 105 kg/s. What is its terminal speed?

An object with cross section A is shot horizontally across frictionless ice. Its initial velocity is v0x at t0=0s. Air resistance is not negligible. A 1.8 m wide, 1.5 m high, 1700 kg car with a drag coefficient of 0.35 hits a very slick patch of ice while going 24 m/s . Air resistance is not negligible. If friction is neglected, how long will it take until the car's speed drops to 11 m/s ? To 5.0 m/s ?

1. A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. (a) What is the initial acceleration of the rocket, assuming you can neglect air resistance? (b) After the rocket has been in flight for a while, burning and exhausting a lot of fuel, its mass has decreased to 1.20 x 105 kg, and...

A 505-g squirrel with a surface area of 920 cm2 falls from a 4.4-m tree to the ground. Estimate its terminal velocity. (Use therag coefficient for a horizontal skydiver. Assume that the cross-sectional area of the squirrel can be approximated as a rectangle of width 11.5 cm and length 23 cm. Note, the squirrel may not reach terminal velocity by the time it hits the ground. Give the squirrel's terminal velocity, not it's velocity as it hits the ground.) ITn/s...
