At what point during a pole-vaulters jump is his gravitational potential energy the greatest?
His gravitational potential energy is greatest at the highest point in his vault. Viewing this problem ideally (where all outside factors are discarded), the pole vaulter's jump follows a parabolic path, and the vaulter will obviously be the furthest distance from the earth's surface when he reaches the highest point in the parabolic path and begins his descent. The gravitational potential energy of a single object with respect to the earth is given by U = mgh, where U is the energy given in joules, m is the mass of the object, g is the gravitational acceleration on earth (around 9.81 m/s2 toward the earth), and h is the positive distance from the earth's surface. In this problem, mass and acceleration are constant, since ideally, the only force acting on the vaulter is the force of gravity that will bring him back to the ground. Therefore, U is maximized at the highest point in the vault - the vertex of the parabola, halfway between the origin of his jump and the point where he hits the ground.
A boy throws a rock straight up in the air It reaches the highest point of its flight after 2.5 seconds how fast was the rock going when it left the boys hand?
There is no way to tell unless a height is specified. Once you have that, you would divide the distance (height) by the time (2.5). Suppose 50 feet, and it took 5 seconds to reach that height. You would have 50/5 = 10 feet per second. given the acceleration of gravity is 9.81m/s2 and y=at2 then ymax = 9.81(2.5)2 OR 61.3125m At its highest point it has a velocity of zero. if 0=v0-at and a=9.81 and t=2.5 then v0 = 9.81(2.5) = 24.525 m/s

What is the acceleration at highest pointn when ball is thrown straight up?
The acceleration at the highest point when a ball is thrown straight up is equal to the acceleration due to gravity, pointing downwards (-9.8 m/s^2). At the highest point, the velocity of the ball is momentarily zero before it starts to fall back down.
Which planets have the largest accelerations of gravity?
The planets with the largest accelerations of gravity are those with the highest surface gravity. Mercury has the highest average surface gravity of all the planets, followed by Venus, Earth, and Mars. Jupiter, with its enormous mass, also has a high gravity acceleration at its cloud tops.
When you jump vertically off the ground what is the acceleration at your highest?
At the highest point of your jump, your acceleration is equal to -9.81 m/s^2, which is the acceleration due to gravity pulling you back towards the ground.
What is the acceleration of a 4kg ball tossed vertically upward when the ball is at its highest point?
The acceleration of the ball at the highest point is equal to the acceleration due to gravity, which is approximately 9.81 m/s^2. At the highest point of its trajectory, the ball momentarily stops moving upward before falling back down due to the force of gravity.
When a ball is thrown up what is its acceleration and velocity at the highest point?
At the highest point, the velocity of the ball is zero because it momentarily stops before falling back down. The acceleration of the ball at the highest point is equal to acceleration due to gravity, which is directed downward toward the center of the Earth and is approximately 9.81 m/s^2.
What is the speed and acceleration of a body thrown vertically upward vertically?
The speed of the body at the highest point is 0 m/s. The acceleration acting on the body is the acceleration due to gravity (-9.81 m/s^2), which acts downward throughout the motion.
An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
A ball tossed vertically upward rises reaches its highest point and then falls back to its starting point during this time the acceleration is always?
The acceleration is always directed downward due to gravity. At the highest point, the acceleration is still acting downward, but its magnitude is zero as the ball momentarily stops before descending back down.
What will the velocity and acceleration be of a ball at its highest trajectory point just before it starts to fall?
At the highest point of its trajectory, the velocity of the ball will be zero since it comes to a stop before falling back down. The acceleration of the ball at this point will be equal to the acceleration due to gravity acting downwards, which is approximately 9.8 m/s^2.
When tossing a coin upwards what happens to its velocity while ascending what happens to its acceleration?
As the coin is tossed upwards, its velocity decreases until it reaches its highest point where it momentarily stops before coming back down. The acceleration due to gravity is acting against the coin's motion, causing it to decelerate while ascending.
A person on a very high cliff throws a ball vertically up at an initial speed of 13.0 ms Neglect friction whats the speed at the highest point the acceleration at the highest point?
At the highest point, the speed of the ball is 0 m/s because it momentarily stops before falling back down. The acceleration at the highest point is equal to the acceleration due to gravity (approximately -9.8 m/s^2) acting in the downward direction.
Which planet has the highest surface gravity of the terrestrial planets?
Mercury has the highest surface gravity of the terrestrial planets. Its gravity is about 0.38 times that of Earth's gravity.
