Question

as a 65kg skydiver falls at terminal velocity, the force of air resistance acting on her isa. 0 Nb. 65 Nc. 650 Nd. 6.5 N

Answer 1

c) 650 N

Explanation

Terminal velocity is defined as the highest velocity attained by an object falling through a fluid.in this case, the fluid is air,

the skydiver falls at a constant velocity as described by Newton's first law of motion. The constant vertical velocity is called the terminal velocity .

Step 1

To calculate terminal velocity: Multiply the mass of the object by the gravitational acceleration

$\begin{gathered} terminal\text{ velocit is when} \\ Drag\text{ force= weight} \end{gathered}$

so

a)let

$\begin{gathered} mass=65\text{ kg} \\ weigth=mg=65\text{ kg*10}\frac{m}{s^2} \\ weigth=650\text{ Newtons} \end{gathered}$

hence, the force of air resistance acting on her is the same ,so the answer is

c) 650 N
