There are two possibilities. One is that he is falling at a constant (positive) speed. In this case, the downward force of gravity is exactly offset by the upward force of drag or air resistance. The parachutist is said to have reached terminal velocity.
The second possibility is that he is moving downwards at a constant speed of zero. He has hit the ground! The parachutist may be said to have reached a terminal situation!

For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
Examples of constant speed but changing acceleration?
A body moving with constant speed in a circular path has acceleration changing at every point.
What will be acceleration of a car moving in a circular motion with constant speed.?
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
How do you use a word constant in a sentence?
I wonder what is the constant speed of this moving car
If a ferris wheel is rotating at constant speed is it moving at a constant velocity?
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
When A parachutist reaches it terminal speed?
When a parachutist reaches terminal speed, the force of air resistance pushing up on the parachutist equals the force of gravity pulling the parachutist downward. At this point, the net force on the parachutist is zero, resulting in a constant velocity.
What happens if a large mass is dropped into something moving at constant speed?
The object that is moving at a constant speed will slow down. Its new velocity will be determined by the original constant speed along with the new combined mass of the moving object and the additional "large mass."
Moving at constant velocity is also moving with constant speed?
Yes, when an object is moving at a constant velocity, it means it is moving with a consistent speed in a straight line. Velocity includes both speed and direction, so if the direction remains constant, the speed must also remain constant.
What is the word for not moving or moving at a constant speed in the same direction?
The word is "stationary" for not moving, and "constant velocity" for moving at a constant speed in the same direction.
Can you use average speed to calculate the speed of an object that is moving at a constant speed?
Yes, average speed can be used to calculate the speed of an object moving at a constant speed. This is because the average speed over a whole journey for an object moving at a constant speed is the same as its actual speed.
Is the momentum of an object moving in a circular path at a constant speed is constant?
determine if the momentum of an object moving in a circular path at constant speed is constant.
Determine if the momentum of an object moving in a circular path at constant speed is constant.?
determine if the momentum of an object moving in a circular path at constant speed is constant.
What does a flat line on a speed vs time graph mean?
it means the object is moving at a constant speed
When the velocity of a moving object stays the same it has a what speed?
When the velocity of a moving object stays the same, it has a constant speed.
What is the difference between moving at a constant speed and not moving at all?
Moving at a constant speed means there is a consistent rate of motion, while not moving at all indicates no change in position. Both scenarios involve no acceleration, but in the case of constant speed, there is still ongoing motion, whereas not moving at all implies stationary position.
How does air resistance affect the way the parachutist falls?
Air resistance, also known as drag, affects the way a parachutist falls by slowing down their descent. As the parachutist falls, the force of air resistance increases with speed, eventually reaching a point where it equals the force of gravity pulling the parachutist down. This creates a situation known as terminal velocity, where the parachutist falls at a constant speed without accelerating further.
What is the speed of a falling parachutist?
The speed of a falling parachutist is around 120 mph (193 km/h) when the parachute is fully deployed. This speed allows the parachutist to descend safely and land without harm.
