Why several seconds after jumping from an aircraft a skydiver will be travelling at a constant speed?
Because you reach maximum velocity.
Would a bullet fired straight up come down with enough velocity to kill?
Yes. It's possible and it has happened several times for real.
A ball is thrown with enough speed straight up so that it is in the air several seconds What is its velocity 2s before it reaches its highest point?
All the time the ball is in the air, its acceleration is 9.8 meters (32.2 feet) per second2 downward. In other words ...Every second it's in the air, its downward speed is that much faster than it was one second earlier.When it reaches its highest point, its speed will be zero.Two seconds earlier, its DOWNWARD speed was that much LESS than it is at the top. In other words ...Its UPWARD speed was that much MORE than it is now.So 2 seconds ago, its upward speed was (2 x 9.8) = 19.6 meters per second / (2 x 32.2) = 64.4 feet per second.
What caused objects to change velocity?
A force, or several forces that don't add up to zero, acting on the object.
Where can I see a picture of a constant velocity joint?

What are the importance of speed velocity and acceleration in sports?
what are important speed, velocity and acceleration in several sports
What is the formula for the angular velocity?
There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.
Why do you have 60 seconds in a minute?
Because 60 has several factors.
What is the formula of velocity?
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
Have any MANNED vehicles reached 'escape velocity' - If so what were they?
Yes, several manned vehicles have reached escape velocity, which is about 25,000 miles per hour. The Apollo spacecraft used during the moon missions reached escape velocity en route to the moon. Also, the Space Shuttle reached escape velocity when it orbited the Earth or traveled to the International Space Station.
Why is Mount Kilimanjaro is important?
It is the highest point in Africa, and supports several different ecosystems at various elevations.
What is a plane figure that is bounded by a straight line?
A plane figure cannot be bounded by only one straight line. If the shape is bounded by lines which are not straight or by several straight lines the answer will depend on exactly what these are.
