What is A football kicked off at an angle 20 from the ground reaches a maximum height of 4.7 m What is the initial velocity of the kick?
To find the initial velocity of the kick, you can use the equation for projectile motion. The maximum height reached by the football is related to the initial vertical velocity component. By using trigonometric functions, you can determine the initial vertical velocity component and then calculate the initial velocity of the kick.

What is the initial velocity of a bullet fired verticaly upward from a gun and reaches a height of 7000 ft?
The initial velocity of the bullet can be obtained by using the kinematic equation for projectile motion. Assuming we neglect air resistance, the initial velocity of the bullet fired vertically upward from a gun can be calculated by setting the final velocity as 0 when it reaches the maximum height of 7000 ft. Using the equation v^2 = u^2 + 2as, where v is the final velocity (0 m/s), u is the initial velocity, a is the acceleration due to gravity, and s is the total displacement. Solve for u to find the initial velocity of the bullet.
Maria throws a ball straight up with an initial velocity of 10 m per s?
As the ball travels up, its velocity decreases until it reaches a maximum height and then starts to fall back down due to gravity. The initial velocity of the ball will determine how high it goes before falling back down.
How can you throw a projectile so that it has zero speed at the top?
To have zero speed at the top, you need to throw the projectile with an initial velocity such that it reaches its maximum height at that point. This requires the initial velocity to be exactly equal to the velocity that would be attained due to gravity when the projectile falls from that height. The angle of projection should be such that the vertical component of the initial velocity cancels out the velocity due to gravity.
1 If you toss a ball upward with a certain velocity it falls freely and reaches a maximum height h What maximum height does the ball reach if you throw it upward with double the initial velocity?
If you throw the ball upward with double the initial velocity, it will reach a maximum height four times greater than the initial height. This is because the maximum height is directly proportional to the square of the initial velocity.
When a rocket reaches maximum height what is its velocity?
A model rocket reaches maximum velocity at the point where the thrust from the engine matches the drag from the air, or the point where the thrust goes to zero when the fuel burns out, whichever comes first.
When a football kicked reaches its maximum height how does its speed compare to its initial speed?
When it's at its maximum height its speed will be zero.
Give example where the velocity of the particle is 0 and acceleration is maximum?
When a pendulum reaches its maximum elongation the velocity is zero and the acceleration is maximum

An object is thrown vertically upward when does it reach maximum height?
when the object reaches maximum height, the velocity of the object is 0 m/s.It reaches maximum height when the gravity of the body has slowed its velocity to 0 m/s. If there is no gravity and there is no external force acting on it then it will never reach a maximum height as there wont be a negativeaccelerationdemonstrated by newtons first law.Where there is and you have the objects initial velocity then you can use :v^2 = u^2+2.a.sv = Velocity when it reaches Max. height so v = 0u = Initial Velocity (m/s)a = Retardation/ Negative Acceleration due to gravity, -9.80m/s ^2And then the unknown (s) is the displacement, or height above ground, and if everything else is in the right format it should be in metres.

What is the final velocity of an object that decreases in kinetic energy and increases in potential energy?
The final velocity of the object would be less than its initial velocity, as some of the kinetic energy has been converted to potential energy. The exact final velocity would depend on the specific amounts of energy involved and the characteristics of the system.
When acceleration is 0 why does velocity have to be at a maximum?
When acceleration is 0, it means there is no change in velocity. At a maximum point, the velocity is either increasing or decreasing, but when it reaches that point, the acceleration is 0.
At what position does a pendulum bob reach its maximum velocity?
The pendulum bob reaches its maximum velocity at the bottom of its swing, when it is passing through the equilibrium position. At this point, all the potential energy has been converted into kinetic energy, resulting in the highest velocity.
How high can a ball go?
The maximum height a ball can reach is dependent on factors such as initial velocity, launch angle, air resistance, and gravity. In a vacuum with no air resistance, the ball will continue to rise until gravity slows it down and makes it come back down.
