1. A raindrop of mass m falls while receiving resistance. Gravitational acceleration is g and it falls to the ground at the final velocity.
(1) Find the final velocity of raindrops when the resistance is air resistance that is proportional to the square of the velocity. Let b be the constant of proportionality.
(2) Find the final velocity of raindrops when the resistance is a viscous resistance proportional to velocity. Let β be the constant of proportionality.

A parachutist whose mass 85 kg drops from a helicopter hovering 2500 m above the ground and falls toward the ground under the influence of gravity. Assume that the force due to air resistance is proportional to the velocity of the parachutist, with the proportionality constant b1=30 N-sec/m when the chute is closed and b2=100 N-sec/m when the chute is open. If the chute does not open until the velocity of the parachutist reaches 20 m/sec, after how many seconds...

Assuming an object has a total mass of M and gravitational constant on earth = g, air resistance = Cd, total surface area = A, initial height = H, and this object has a thruster (assuming constant thrust = F_thrust) that ignites at a time T_ignition and stops burning at time T_turnoff (T_turnoff and T_ignition occur at different time during the process), please derive an equation for the velocity of this linear vertical motion as a function of time, V(t).

A bullet with speed 511 m/s and mass m = 5.00 g is shot into a stationary block of wood hanging a distance h1 = 1.00 m above the ground, as shown in Figure 1. The block is hanging by a string of length r = 0.30 m. The bullet is lodged in the block, and the block-bullet system swings so that the string makes an angle of θ = 60.0° when the string breaks, as shown in Figure 2....
