I'm not being snide but for the life of me cannot think of any other method.
The one option which might not be considered strictly as kinematics is by using energy: the potential and kinetic energies under these conditions will be constant. So develop an eqn that uses both. But given the data, this is the only approach.
If you use an alternate approach (and yes, there is one) using the basic kinematic equation of motionwhiteruskii said:Attending class would be wonderful...last week was beyond my control
anyways, not to go off on a tangent, using mgh=1/2mv^2, I canceled out mass, since it's just a multiplier to both, and got an answer of approximately 10.95. Does that seem about right?
The velocity of a pole vaulter is calculated by dividing the distance they traveled over a certain interval by the time it took them to travel that distance. In this case, the distance is 10.95 meters and the time is not specified.
A velocity of 10.95 m/s means that the pole vaulter is traveling at a speed of 10.95 meters per second. This is a relatively fast velocity and indicates that the pole vaulter is moving quickly towards the bar.
The velocity of a pole vaulter is affected by their approach in two ways: the length of the approach and the speed at which they run during the approach. A longer approach allows for a higher velocity, while a faster run during the approach also increases velocity.
A velocity of 10.95 m/s is a relatively common velocity for pole vaulters, especially at the elite level. However, velocities can vary depending on the individual's technique and physical abilities.
The velocity of a pole vaulter is a crucial factor in their jump. A higher velocity allows the vaulter to generate more momentum and energy, which can help them clear the bar at a higher height. It also affects the angle at which they approach the bar, which can impact the success of the jump.
