If he's moving with constant velocity, then the net force on him is zero.
The force of gravity must be exactly balanced by the force of kinetic friction
between him and the air.
An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.
When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.
because water has higher viscosity than air so resisting the movement of the body in it more than air so decreasing the velocity
Zero. "Terminal velocity" means that the object is no longer accelerating; the downward force of gravity and the upward force of resistance are in balance.
Terminal velocity for a kangaroo penis is not a meaningful concept, as terminal velocity refers to the constant speed that a freely falling object eventually reaches when the resistance of the medium it is moving through equals the force of gravity. Kangaroo penises do not fall freely in this manner.
For the most part, yes; once at terminal velocity, there is no acceleration, so it has direction.
Terminal Velocity.
No, a skydiver's acceleration remains constant as they fall towards their terminal velocity. This is because terminal velocity is the point at which the forces of gravity and air resistance are balanced, resulting in a constant velocity.

the greatest velocity a falling object reaches is terminal velocity
Yes, you can survive terminal velocity if you have the proper equipment, such as a parachute, to slow down your fall before reaching the ground. Terminal velocity is the maximum speed an object reaches when falling through the air, and with the right precautions, it is possible to survive a fall from this height.
the greatest velocity a falling object reaches is terminal velocity
Terminal velocity.
terminal velocity
Yes, but only in free-fall. If I'm driving at 60 mph, I have a constant velocity, but it's not my "terminal velocity" in the sense that there is no limit to my acceleration caused by air friction. But yes, an object in free-fall reaches its terminal velocity when its velocity stops increasing (acceleration=0).
At terminal velocity, the acceleration of a falling object is zero. Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium (such as air) through which it is falling equals the force of gravity.
The greatest velocity a falling object reaches is called the terminal velocity.For an object falling at the terminal velocity, the weight force of the objectis balanced by the drag force and buoyant force on the object.W + FDRAG + FBUOYANT = FNET = 0.0
