The only force acting on a projectile once launched is gravity. So the acceleration of any object launched at any angle is the acceleration due to gravity, -9.8m/s2.

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 is the acceleration of gravity, downwards, or 9.8m/s/s (32 ft/s/s). When ball is thrown straight up it has an initial velocity that is decreasing because of gravity; at the highest point velocity is zero but acceleration is always constant at gravity rate.
An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
When is fuel consumption at its highest?
it is at its higher at acceleration
What will the velocity and acceleration be of a ball at its highest trajectory point just before it starts to fall?
The acceleration of the ball (after it leaves the thrower's hand) is the acceleration due to gravity, g.1 The vertical velocity of the ball at its apex is zero. The horizontal velocity is constant throughout the ball's flight; it is whatever it was at the outset of its arc.2 ---------------- 1. The acceleration due to gravity, g, is -9.8 m/s2 or -32.2 ft/s2. 2. Ignoring the effects of air resistance, which tend to slow things down.
Is it possible for a body to have zero velocity and non-zero acceleration?
Answer:Yes, but only instantaneously.Consider a thrown ball moving directly upward. At the highest point of its trajectory, the instanataneous velocity (the velocity at that precise instant) is zero even while the acceleration due to gravity remains non zero.
What is the acceleration of a 4kg ball tossed vertically upward when the ball is at its highest point?
No matter what the mass of the ball is, or what direction you toss it, it has the same acceleration from the moment it leaves your hand until it hits the ground ... the acceleration due to gravity, on Earth or wherever you're playing the game, pointing down. On Earth, it's 9.8 meters (32.2 feet) per second2.
Where on a roller coaster is potential energy at the highest?
Potential energy is highest at the dead top of the highest point on the roller coaster. It is lowest at the lowest point. Kinetic energy (motion energy) is highest at the point where the velocity is highest. This depends on the design. A good guess is dead bottom of the longest fall, but on a complex coaster ride there are other possibilities. Also, air resistance and friction can change this.
