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?

Multiply the height by 4.
The equation to use is h=-16t2 + v0t + h0.
Use whatever values you want for v0 and h0, and find the vertex of the parabola. Then double your value of v0, and find the vertex of your new parabola. It will be 4 times as high every time.
By the way, to find the vertex, plug in v0/32 for t. Then solve for h.

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?
initial velocity of the kick = 28.06 m/s
How do you calculate maximum velocity of a falling object?
Without air, the speed of a falling object keeps increasing, and never reaches a maximum. The only thing that causes it to reach a maximum and stop increasing is air resistance. The effects of air resistance depend on the size, shape, and composition of the object, and the calculation of the "terminal velocity" in advance is very complex.
How high can a ball go?
The maximum height of a thrown ball is dependent on the upward portion of the initial velocity. Air friction will slow it somewhat but gravity will cause it to lose most of its upward velocity. The velocity will decrease by 9.8 m/sec for each second of its upward motion, until it reaches zero. At that point, the ball is pulled back toward Earth.
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.
True or False terminal velocity is the velocity a speeding object reaches when it crashes?
Technically, its false.... Terminal Velocity is defined as "the constant maximum velocity reached by an object falling through the atmosphere under the attraction of gravity". The crash is simple a result of and the conclusion to the fall....

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.
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.
What is the final velocity of an object that decreases in kinetic energy and increases in potential energy?
Its final velocity will be zero when it reaches maximum potential energy.

What is the name of an object in free fall?
Terminal velocity. It is when something falls through a gas or liquid it accelerates, at a decreasing rate, until it reaches its maximum constant velocity.
What is the greatest velocity a falling object reaches?
the greatest velocity a falling object reaches is terminal velocity
How do you pack a powerful punch?
You will need to know the distance between you and the target. The reason for knowing the distance is for making sure that your fist reaches the maximum velocity before it hits your target. This maximum velocity is usually happens before your fist reaches its maximum reach. Upon its maximum reach, the velocity of your fist instantly drops from maximum to zero. Practice, practice, practice. The traditional martial artist punches a makiwara, a padded board the flexes when correctly punched. It helps teach the proper focus, ranges, and the ability to put the entire body behind the punch, creating maximum power.
