A paratrooper and his 8-m-diameter parachute weigh 950 N. Taking the average air density to be 1.2 kg/m3, determine the terminal velocity of the paratrooper.

The terminal velocity of a person falling in air depends upon the weight and the area of the person facing the fluid. Find the terminal velocity (in meters per second and kilometers per hour) of an 88.0 kg skydiver falling in a pike (headfirst) position with a surface area of 0.150 m2. (Assume that the density of air is 1.21 kg/m³ and the drag coefficient of a skydiver in a pike position is 0.7. For each answer, enter a number.) terminal velocity in m/s |m/s terminal velocity in km/h km/h

A diver has a mass of 91 kg and a volume of 0.04 m^3.  What is the downwards acceleration, in m/s^2, experienced by the diver while he is in the ocean?

d) Figure Q1(d) shows streamlines representing the flow of air over the wing of a plane. Which of the eight vectors A-H most accurately represents the resultant force on the wing due to the air flow over it? You do not have to justify your choice. c↑ D1 B E A H Figure Q1(d): Air flows over the wing of a plane.

An observation balloon has a volume of 300 m² and is filled with hydrogen. The basket and passengers have a total mass of 350 kg. Find the initial acceleration when the balloon is released (assume air resistance to be zero when velocity is zero). The upward force on the balloon is equal to the weight of air displaced by the balloon.

The terminal velocity of a person falling in air depends upon the weight and the area of the person facing the fluid. Find the terminal velocity (in meters per second and kilometers per hour) of a 90.5-kg skydiver falling in a pike (headfirst) position with a surface area of 0.130 m2. (Assume that the density of air is 1.21 kg/m³ and the drag coefficient of a skydiver in a pike position is 0.7.) m/s km/h Additional Materials Reading
